                               Dear Shareholder,

      [photo]                  As we advised you at year end, we don't expect 1997's stock market to report the record-breaking 
                               returns we saw last year. However, we do believe it may be a period in which investors can take 
Bridget A. Macaskill           advantage of some great buying opportunities created by lower stock valuations. Our optimism can 
President                      be traced to solid economic fundamentals that should remain stable throughout the calendar year 
Oppenheimer                    and the robust investing habits of aging baby boomers.
Discovery Fund                      First, the economy has been expanding slowly, but steadily. Interest rates have remained 
                               relatively low despite the Federal Reserve's recent increase in short-term rates. In turn, low 
                               interest rates translate into reduced borrowing rates for companies and individuals. Companies 
                               have taken advantage of the savings by using it to improve their technologies, thereby increasing 
                               their productivity and efficiency. By downsizing and implementing other cost-cutting strategies, 
                               companies in the United States should now be better equipped to compete globally. 
                                   In addition, inflation has been at its lowest level in three decades. While it's true that an 
                               increase in interest rates often indicates an accelerating economy, the Federal Reserve has been 
                               quick to acknowledge that inflation and growth are under control. In fact, they've labeled the 
                               recent move as a "preemptive" act to keep inflation at these low levels and extend the economy's 
                               healthy growth cycle. 
                                   Second, monthly cash flows into mutual funds have been higher, largely due to the savings 
                               pattern of the baby boomers. The first wave of this generation--those just turning 50--are beginning
                               to direct more money toward their retirement. Concerned about proposed cutbacks in Social 
                               Security benefits, more and more individuals believe they will have to fund a large portion of 
                               their retirement themselves. And, as they gradually pay off their children's college expenses and 
                               reduce their mortgages, they are positioned to save more aggressively. 
                                   For these reasons we remain confident about the opportunities available in the stock market 
                               this year. Of course, selectivity will be the key to allocating an effective portfolio. 
                               Therefore, it will be important to base choices on the individual merits of a company, such as 
                               strong management, fundamental business policies and long-term prospects for the future. And for 
                               investors, as always, maintaining a long-term time horizon is essential. Because, while 
                               short-term swings will certainly occur and past performance is no guarantee of future results, 
                               the markets long-term trend has been to move higher and higher.
                                   Your portfolio managers discuss the outlook for your Fund in light of these broad issues on 
                               the following pages. Thank you for your confidence in OppenheimerFunds, THE RIGHT WAY TO INVEST.  
                               We look forward to helping you reach your investment goals in the future.

                               Q + A


                               An interview with your Fund's managers.

Q   What areas                 HOW HAS THE FUND PERFORMED?
are you currently 
targeting?                     Because investors had a preference for more conservative, large-cap stocks during the second half 
                               of 1996, the performance of small-cap investments has been relatively disappointing. However, as 
                               the momentum between small- and large-cap stocks has historically swung back and forth, we do not 
                               view the current trend as either unusual or permanent. Indeed, Oppenheimer Discovery Funds 
                               universe of emerging-growth stocks has become attractively valued and appears poised to perform 
                               much better over the intermediate to long term.
                               WHAT INVESTMENTS MADE POSITIVE CONTRIBUTIONS TO PERFORMANCE?
                               The energy sector, specifically the oil-services group, clearly produced the most gains during 
                               the past six months. Improved business fundamentals led to significant earnings gains for many of 
                               these companies; in particular, the Funds offshore-drilling companies benefited from higher 
                               activity and better pricing.
                                   In addition, several of the Fund's technology holdings made positive contributions to 
                               performance. For example, we held shares of a software company that leads the market for 
                               anti-virus products. Thanks to the convenient way the Internet allows sharing information across 
                               the globe, this business has enjoyed explosive growth in sales and profits as computer system 
                               owners worked to protect their systems from corruption.(1)
                               WERE THERE ANY INVESTMENTS THAT PERFORMED POORLY?
                               The general malaise in the small-cap market tainted most small-cap performance this period, 
                               including companies within the healthcare sector. This was partly a result of fears about future 
                               cuts in Medicare and Medicaid reimbursement.


                               (1) The Fund's portfolio is subject to change.

                               We follow a bottom-up stock selection process. We begin by researching individual companies

Executive VP, Director of      company's sustainability of that growth in light of market demand for the company's products and/or
Equity Investments             services, as well as the strength of its competitive positions. Based on this information, we
                               make our selections, bearing in mind that while an industry may be out of favor, strong
Bottom: Michael Levine,        individual companies can still make sense as investments for the Fund's portfolio.
Member of Equity                   Lately, we have made several selections within the energy sector. These stocks earned

                               good performance through 1997 and into next year.

                             NOTES TO FINANCIAL STATEMENTS   (Unaudited)

- --------------------------------------------------------------------------------
1. SIGNIFICANT               Oppenheimer Discovery Fund (the Fund) is registered
   ACCOUNTING POLICIES       under the Investment Company Act of 1940, as 
                             amended, as a diversified, open-end management 
                             investment company. The Fund's investment 
                             objective is capital appreciation; current 
                             income is not an objective. In seeking its 
                             objective, the Fund emphasizes investments in 
                             securities of "growth-type" companies, 
                             including common stocks, preferred stocks, 
                             convertible securities, rights, warrants and 
                             options. The Fund's investment adviser is 
                             OppenheimerFunds, Inc. (the Manager). The Fund 
                             offers Class A, Class B, Class C and Class Y 
                             shares. Class A shares are sold with a 
                             front-end sales charge. Class B and Class C 
                             shares may be subject to a contingent deferred 
                             sales charge. All classes of shares have 
                             identical rights to earnings, assets and voting 
                             privileges, except that each class has its own 
                             expenses directly attributable to a particular 
                             class and exclusive voting rights with respect 
                             to matters affecting a single class. Classes A, 
                             B and C have separate distribution and/or 
                             service plans.  No such plan has been adopted 
                             for Class Y shares. Class B shares will 
                             automatically convert to Class A shares six 
                             years after the date of purchase.  The 
                             following is a summary of significant 
                             accounting policies consistently followed by 
                             the Fund.

                             INVESTMENT VALUATION.  Portfolio securities are 
                             valued at the close of the New York Stock 
                             Exchange on each trading day. Listed and 
                             unlisted securities for which such information 
                             is regularly reported are valued at the last 
                             sale price of the day or, in the absence of 
                             sales, at values based on the closing bid or 
                             the last sale price on the prior trading day. 
                             Long-term and short-term "non-money market" 
                             debt securities are valued by a portfolio 
                             pricing service approved by the Board of 
                             Trustees. Such securities which cannot be 
                             valued by the approved portfolio pricing 
                             service are valued using dealer-supplied 
                             valuations provided the Manager is satisfied 
                             that the firm rendering the quotes is reliable 
                             and that the quotes reflect current market 
                             value, or are valued under consistently applied 
                             procedures established by the Board of Trustees 
                             to determine fair value in good faith. 
                             Short-term "money market type" debt securities 
                             having a remaining maturity of 60 days or less 
                             are valued at cost (or last determined market 
                             value) adjusted for amortization to maturity of 
                             any premium or discount.

                             REPURCHASE AGREEMENTS.  The Fund requires the 
                             custodian to take possession, to have legally 
                             segregated in the Federal Reserve Book Entry 
                             System or to have segregated within the

                             collateral for repurchase agreements. The 
                             market value of the underlying securities is

                             price at the time of purchase. If the seller of 
                             the agreement defaults and the value of the 
                             collateral declines, or if the seller enters an 
                             insolvency proceeding, realization of the value 
                             of the collateral by the Fund may be delayed or

                             ALLOCATION OF INCOME, EXPENSES, AND GAINS AND 
                             LOSSES.  Income, expenses (other than those 
                             attributable to a specific class) and gains and 
                             losses are allocated daily to each class of 
                             shares based upon the relative proportion of 
                             net assets represented by such class. Operating 
                             expenses directly attributable to a specific 
                             class are charged against the operations of 
                             that class.

                             FEDERAL TAXES.  The Fund intends to continue to 
                             comply with provisions of the Internal Revenue 
                             Code applicable to regulated investment 
                             companies and to distribute all of its taxable 
                             income, including any net realized gain on 
                             investments not offset by loss carryovers, to 
                             shareholders. Therefore, no federal income or 
                             excise tax provision is required.

                             TRUSTEES' FEES AND EXPENSES.  The Fund has 
                             adopted a nonfunded retirement plan for the 
                             Fund's independent trustees. Benefits are based 
                             on years of service and fees paid to each 
                             trustee during the years of service. During the 
                             six months ended March 31, 1997, a provision of 
                             $9,457 was made for the Fund's projected 
                             benefit obligations, and payments  of $11,664 
                             were made to retired trustees, resulting in an 
                             accumulated liability of $194,740 at March 31, 
                             1997.

                             DISTRIBUTIONS TO SHAREHOLDERS.  Dividends and 
                             distributions to shareholders are recorded on 
                             the ex-dividend date.

                             CLASSIFICATION OF DISTRIBUTIONS TO 
                             SHAREHOLDERS.  Net investment income (loss) and 
                             net realized gain (loss) may differ for 
                             financial statement and tax purposes. The 
                             character of the distributions made during the 
                             year from net investment income or net realized 
                             gains may differ from their ultimate 
                             characterization for federal income tax 
                             purposes. Also, due to timing of dividend 
                             distributions, the fiscal year in which amounts 
                             are distributed may differ from the year that 
                             the income or realized gain was recorded by the 
                             Fund.

1. SIGNIFICANT               OTHER.  Investment transactions are accounted for 
   ACCOUNTING POLICIES       on the date the investments are purchased or sold 
   (CONTINUED)               (trade date) and dividend income is recorded on the
                             ex-dividend date. Realized gains and losses on 
                             investments and unrealized appreciation and 
                             depreciation are determined on an identified 
                             cost basis, which is the same basis used for 
                             federal income tax purposes.
                                  The preparation of financial statements in 
                             conformity with generally accepted accounting 
                             principles requires management to make 
                             estimates and assumptions that affect the 
                             reported amounts of assets and liabilities and 
                             disclosure of contingent assets and liabilities 
                             at the date of the financial statements and the 
                             reported amounts of income and expenses during 
                             the reporting period. Actual results could 
                             differ from those estimates.

                             on sales of Class A shares totaled $2,704,391, 
                             of which $920,512 was retained by

                             distributor, and by an affiliated 
                             broker/dealer. Sales charges advanced to 
                             broker/dealers by OFDI on sales of the Fund's 
                             Class B and Class C shares totaled $2,639,827 
                             and $124,527, of which $275,539 and $4,104, 
                             respectively, was paid to an affiliated 
                             broker/dealer. During the six months ended 
                             March 31, 1997, OFDI received contingent 
                             deferred sales charges of $195,774 and $11,461

                             as reimbursement for sales commissions advanced 
                             by OFDI at the time of sale of such shares.
                                  OppenheimerFunds Services (OFS), a 
                             division of the Manager, is the transfer and 
                             shareholder servicing agent for the Fund, and 
                             for other registered investment companies. 
                             OFS's total costs of providing such services 
                             are allocated ratably to these companies.
                                  The Fund has adopted a Service Plan for 
                             Class A shares to reimburse OFDI for a portion 
                             of its costs incurred in connection with the 
                             personal service and maintenance of accounts 
                             that hold Class A shares. Reimbursement is made 
                             quarterly at an annual rate that may not exceed 
                             0.25% of the average annual net assets of Class 
                             A shares of the Fund. OFDI uses the service fee 
                             to reimburse brokers, dealers, banks and other 
                             financial institutions quarterly for providing 
                             personal service and maintenance of accounts of 
                             their customers that hold Class A shares. 
                             During the six months ended March 31, 1997, 
                             OFDI paid $101,163 to an affiliated 
                             broker/dealer as reimbursement for Class A 
                             personal service and maintenance expenses.
                                  The Fund has adopted a reimbursement type 
                             Distribution and Service Plan for Class B 
                             shares to reimburse OFDI for its services and 
                             costs in distributing Class B shares and 
                             servicing accounts. Under the Plan, the Fund 
                             pays OFDI an annual asset-based sales charge of 
                             0.75% per year on Class B shares. OFDI also 
                             receives a service fee of 0.25% per year to 
                             reimburse dealers for providing personal 
                             services for accounts that hold Class B shares. 
                             Both fees are computed on the average annual 
                             net assets of Class B shares, determined as of 
                             the close of each regular business day. During 
                             the six months ended March 31, 1997, OFDI paid 
                             $11,054 to an affiliated broker/dealer as 
                             reimbursement for  Class B personal service and 
                             maintenance expenses and retained $902,504 as 
                             reimbursement for Class B sales commissions and 
                             service fee advances, as well as financing 
                             costs. If the Plan is terminated by the Fund, 
                             the Board of Trustees may allow the Fund to 
                             continue payments of the asset-based sales 
                             charge to OFDI for certain expenses it incurred 
                             before the Plan was terminated. As of March 31, 
                             1997, OFDI had incurred unreimbursed expenses 
                             of $6,836,261 for Class B.
                                  The Fund has adopted a compensation type 
                             Distribution and Service Plan for Class C 
                             shares to compensate OFDI for its services and 
                             costs in distributing Class C shares and 
                             servicing accounts. Under the Plan, the Fund 
                             pays OFDI an annual asset-based sales charge of 
                             0.75% per year on Class C shares. OFDI also 
                             receives a service fee of 0.25% per year to 
                             compensate dealers for providing personal 
                             services for accounts that hold Class C shares. 
                             Both fees are computed on the average annual 
                             net assets of Class C shares, determined as of 
                             the close of each regular business day. During 
                             the six months ended March 31, 1997, OFDI 
                             retained $84,711 as compensation for Class C 
                             sales commissions and service fee advances, as 
                             well as financing costs. If the Plan is 
                             terminated by the Fund, the Board of Trustees 
                             may allow the Fund to continue payments of the 
                             asset-based sales charge to OFDI for certain 
                             expenses it incurred before the Plan was 
                             terminated. As of March 31, 1997, OFDI had 
                             incurred unreimbursed expenses of $310,201 for 
                             Class C.

5. FUTURES CONTRACTS         The Fund may buy and sell interest rate futures 
                             contracts in order to gain exposure to or protect 
                             against changes in interest rates. The Fund may 
                             also buy or write put or call options on these 
                             futures contracts.
                                  The Fund generally sells futures contracts to 
                             hedge against increases in interest rates and the 
                             resulting negative effect on the value of fixed 
                             rate portfolio securities. The Fund may also 
                             purchase futures contracts to gain exposure to 
                             changes in interest rates as it may be more 
                             efficient or cost effective than actually buying 
                             fixed income securities.

5. FUTURES CONTRACTS         Upon entering into a futures contract, the Fund is 
   (CONTINUED)               required to deposit either cash or securities in an
                             amount (initial margin) equal to a certain 
                             percentage of the contract value. Subsequent 
                             payments (variation margin) are made or received by
                             the Fund each day. The variation margin payments 
                             are equal to the daily changes in the contract 
                             value and are recorded as unrealized gains and 
                             losses. The Fund recognizes a realized gain or 
                             loss when the contract is closed or expires.
                                  Securities held in collateralized accounts to 
                             cover initial margin requirements on open futures 
                             contracts are noted in the Statement of 
                             Investments. The Statement of Assets and 
                             Liabilities reflects a receivable or payable for 
                             the daily mark to market for variation margin.
                                  Risks of entering into futures contracts (and
                             related options) include the possibility that 
                             there may be an illiquid market and that a change 
                             in the value of the contract or option may not 
                             correlate with changes in the value of the 
                             underlying securities.

                             At March 31, 1997, the Fund had outstanding 
                             futures contracts as follows:

6. ILLIQUID AND              At March 31, 1997, investments in securities 
   RESTRICTED SECURITIES     included issues that are illiquid or restricted. 
                             Restricted securities are often purchased in 
                             private placement transactions, are not registered 
                             under the Securities Act of 1933, may have 
                             contractual restrictions on resale, and are valued 
                             under methods approved by the Board of Trustees as 
                             reflecting fair value. A security may be considered
                             illiquid if it lacks a readily-available market or
                             if its valuation has not changed for a certain 
                             period of time. The Fund in tends to invest no more
                             than 10% of its net assets (determined at the time
                             of purchase and reviewed from time to time) in 
                             illiquid or restricted securities. Certain 
                             restricted securities, eligible for resale to 
                             qualified institutional investors, are not subject
                             to that limit. The aggregate value of illiquid or 
                             restricted securities subject to this limitation at
                             March 31, 1997 was $17,316,391, which represents 
                             1.42% of the Fund's net assets. Information 
                             concerning restricted securities is as follows:
