Sidebar text: Wealth takes a lifetime to build. Once achieved, it should 
be preserved.

I'm pleased to report that over the past 12 months, the Nuveen Select Portfolios
have continued to perform well, meeting their primary objective of providing you
with competitive levels of tax-free income. The Select Portfolios are a uniquely
structured group of investments designed to achieve income stability over a
defined term. These portfolios were established in 1992 as a source of
dependable tax-free income with a set maturity schedule. Their fixed-portfolio
structure, defined life cycle, and emphasis on income stability make these
portfolios the ideal choice for investors who want the income and maturity of
individual bonds enhanced by the ongoing surveillance and diversification
provided by Nuveen. The strong market in fixed-income securities during the
year, bolstered by investor demand for quality investments like our Select
Portfolios benefited the funds. Competitive tax-free income, enhanced by strong
share price performance, illustrates once again that municipal bonds provide an
excellent investment for income-oriented investors.


The Economy in Review
Over the past year, the markets endured bouts of volatility, as the Asian
financial crisis spilled over into emerging markets and affected economies
around the globe. Investors responded by seeking a haven from the ongoing
uncertainty in more conservative investments, such as municipal bond funds. As
interest rates on municipal bonds continued to trend downward, the competitive
yields offered by our exchange-traded portfolios stimulated additional investor
interest.

The market for exchange-traded municipal bond funds has been exceptionally
strong. Exchange-traded funds continue to represent a bright spot among
fixed-income investments. These funds have paid competitive current market
yields in a market that places a high premium on yield. As of September 30,
1998, the yields for the Nuveen Insured California Select Tax-Free Income
Portfolio (NXC) and the Nuveen Insured New York Select Tax-Free Income Portfolio
(NXN) were 5.01% and 5.16%, respectively. The yields for the Nuveen Select
Tax-Free Income Portfolio (NXP), Nuveen Select Tax-Free Income Portfolio 2
(NXQ), and Nuveen Select Tax-free Income Portfolio 3 (NXR) were 5.45%, 5.35%,
and 5.26%, respectively.

In the coming months, we will continue to watch several key factors affecting
the future of the economy, including the strength of the dollar, employment
figures, corporate earnings reports, and further interest rate indications from
the Federal Reserve. These factors will influence the outlook for fixed-income
markets during the remainder of the year.


Municipal Market Review
Over the past year, the declining interest rate environment drove yields on
30-year Treasuries to their lowest levels since the U.S. government began
selling these bonds in 1977. The story in the municipal market, however, was
quite different. As yields on the long Treasury bond reached historic lows, the
yield on the Bond Buyer 40, an unmanaged index of long-term municipal bonds,
fell just 49 basis points - from 5.53% to 5.04% - compared with the dramatic
113-basis point drop in Treasury yields over the past 12 months. As of September
24, 1998, the ratio between Treasury yields and municipal yields stood at
100.6%, compared with the more typical range of 80-90%. For investors, this
means that municipal bonds offered 100.6% of the yield of a Treasury bond with
comparable characteristics - before taxes are taken into account. On an
after-tax basis, municipal bonds present an even more attractive investment
option in relation to Treasuries.
<PAGE>
One of the main factors in the steep decline in Treasury yields was the strong
interest in these investments by international investors. As the economic
turmoil in Asia continued to spread to other economies world-wide and the dollar
strengthened against foreign currencies, the demand for U.S.-dollar denominated
Treasury securities increased.

In the municipal market, where foreign demand was limited by the inapplicability
of tax advantages, low interest rates and a strong economy combined to generate
high levels of new issuance and a dramatic increase in the refinancing of
existing bonds. The first six months of 1998 saw $146 billion of new municipal
bond issuance, up 51% over the same period in 1997, and $42 billion in refunding
activity, an increase of 118% from last year. The continued strength of the U.S.
economy has brought about improvements in the fundamental financial health of
many municipalities and boosted the overall credit quality of municipal bonds.
This enhanced credit quality also contributed to the fund's performance, as the
upgraded bonds increased in value.


Nuveen Expertise Is Key
The key to taking advantage of the exceptional values currently available in the
municipal market is the expertise of a proven investment manager. At Nuveen, we
recognize the value of time-tested expertise. The high level of recent municipal
issuance, for example, highlights the value of Nuveen's detailed knowledge of
the municipal market, as our portfolio management teams carefully analyze the
flood of issues to select those securities best suited to helping the funds
achieve their investment objectives.

In addition, Nuveen has assembled a group of Premier AdvisersSM that can provide
years of experience and insight dealing with a given asset class. In addition to
Nuveen Advisory Corporation, our Premier Adviser for tax-free investing, you can
rely on our growing group of other advisers to provide the expertise that makes
the difference in the equity market, including Institutional Capital Corporation
for value investing and Rittenhouse Financial Services for growth investing. For
more information about our funds, including charges and expenses, contact your
financial adviser for a prospectus, or call Nuveen at (800) 621-7227. Read it
carefully before you invest or send money.

We encourage you to talk with your financial adviser about the ways Nuveen's
expanding selection of investments, together with our 100 years of market
experience, can help you establish the foundation of a diversified portfolio
designed to build and sustain long-term financial security. When seeking quality
investment solutions that withstand the test of time, you can count on Nuveen.
Our expertise provides the key to building a well-balanced portfolio that can
help you achieve your financial goals.

Sincerely,


Timothy R. Schwertfeger
Chairman of the Board

Nuveen Select Portfolios
Portfolio Manager Roundtable

Portfolio managers Dan Solender and Mike Davern discuss the current municipal
market environment, portfolio performance, and the outlook for the Nuveen Select
Portfolios. Dan and Mike assumed management responsibilities for the portfolios
on July 1, 1998, as part of Nuveen's efforts to maximize the efficient use of
staff resources and portfolio manager expertise. Dan is a six-year veteran of
Nuveen with 11 years of investment experience; his management duties include the
national and New York Select Portfolios as well as additional New York municipal
bond funds. Mike, who joined Nuveen in 1996, has 15 years of experience as an
investment professional and manages a range of Nuveen state municipal bond funds
in addition to the California Select Portfolio.





Municipal Market Update
The third quarter of 1998 saw an acceleration of trends that have been apparent
in the credit markets over the past 12 months: declining interest rates and an
increased ratio between municipal and Treasury yields. The cause in both cases
was heightened concern about the condition of the global financial system. While
the U.S. economy exhibited continued growth, the impact of the financial turmoil
in Southeast Asia, Russia, and other emerging markets began to be felt in the
U.S. equity market. A desire to cushion this impact and avert a domestic credit
crunch prompted the Federal Reserve to ease short-term interest rates in late
September, the first rate cut in almost three years. Concerned that the
quarter-point cut might not be enough, the Fed acted to reduce rates again in
mid-October and in mid-November, bringing the federal funds rate to 4.75%. The
Fed indicated these moves were intended to keep inflation low and to sustain
U.S. economic growth going forward.

In response to this environment of low interest rates and continued economic
growth, municipal bond issuance over the past year has been among the heaviest
in years. In recent months, volatility in the equity markets has boosted demand
for municipal bonds as well. Demand from institutional buyers such as insurance
companies has also increased, as these investors recognized the exceptionally
attractive values currently offered by municipal bonds.

Fund Performance
For the 12 months ended September 30, 1998, the national Nuveen Select
Portfolios produced total returns on net asset value that ranged from 6.79% to
7.74%, providing taxable-equivalent returns of 9.45% to 10.31% for investors in
the 31% federal income tax bracket. For the same period, the Nuveen Insured
California Select Tax-Free Income Portfolio (NXC) posted a total return of 7.75%
on net asset value, while the Nuveen Insured New York Select Tax-Free Income
Portfolio (NXN) returned 7.35%, providing investors in the combined federal and
state income tax bracket (California 37.4%; New York 35.7%) with
taxable-equivalent returns of 10.99% and 10.34%, respectively. These total
returns compare with the Lehman Brothers Municipal Bond Index's annual return of
8.71% (the benchmark for NXP, NXQ, and NXR), the Lehman California Insured
Municipal Bond Index's 9.79% (for NXC), and the Lehman New York Insured
Municipal Bond Index's 9.43% (for NXN).

Much of the portfolios' performance over the past 12 months can be tied to
duration. Duration measures a bond portfolio's price volatility, or reaction to
interest rate movements. The longer the duration, the more sensitive the
portfolio is to changes in interest rates. During a period of falling interest
rates, longer duration enables a portfolio to participate more fully in market
gains. However, when rates rise, longer duration can make the portfolio more
vulnerable to potential price declines. As interest rates trended downward,
portfolios with durations shorter than the relevant index generally tended to
underperform the market. The following chart illustrates the durations of the
funds and the applicable Lehman Brothers Index, as of September 30, 1998.

- ----------------------------------------------------------------

In the low interest rate environment of the past year, good call protection
helped support the dividends of NXP, NXR, and NXN and protect the income of
these funds from erosion. These three funds have now provided shareholders with
17, 27, and 66 consecutive months, respectively, of steady income. However,
declining interest rates also played a role in reducing the income levels of NXQ
and NXC, as proceeds from higher-yielding bonds called or sold from these
portfolios were reinvested in bonds paying today's lower interest rates. Over
the past year, the change in income level earned by these portfolios
necessitated dividend reductions. Despite the adjustments in these two funds,
the Select Portfolios continue to provide very competitive current market yields
ranging from 5.01% to 5.45%, equivalent to taxable yields of 7.26% to 7.90% for
investors in the 31% federal tax bracket. Taking into account the state taxes in
California and New York, the taxable-equivalent yields for NXC and NXN were
8.00% and 8.02%, respectively.
<PAGE>
As Tim mentioned in his letter to shareholders, share price performance among
the Nuveen exchange-traded portfolios has been strong over the past 12 months.
As interest rates fell, active demand for quality portfolios such as the Nuveen
Select Portfolios benefited share prices and eliminated the slight discounts to
net asset value of a year ago. As of September 30, 1998, all of the portfolios
were trading at premiums ranging from 0.30% to 4.83% above their net asset
values.

Key Strategies
The Select Portfolios are a uniquely structured group of investments designed
and managed to achieve income stability over a defined term. The portfolios
provide income and maturity similar to that of individual bonds, with the
additional benefit of ongoing credit surveillance. Maintaining stable tax-free
dividends is the top priority for each of these portfolios, and our strategies
continue to focus on achieving this objective. We buy and sell bonds within
these portfolios only to take advantage of opportunities to enhance income,
credit quality, or portfolio structure. Over the past 12 months, such trading
was effectively limited by the prevailing environment of falling interest rates
and low yields because all of the bonds in these portfolios were purchased at
higher rates than those currently being offered. The portfolios' short durations
offered excellent protection from price volatility.

Outlook for the Future
The current market environment - influenced by declining interest rates, benign
inflation, and strong municipal supply - has helped to position municipal bonds
as one of the most compelling values in today's marketplace. We expect that the
excellent municipal-to-Treasury ratio, combined with continued volatility in the
equity markets and investors' increasing awareness of the need for asset
allocation rebalancing, will result in growing demand for these bonds. We
believe that investors who take advantage of current opportunities in the
municipal market should be rewarded with healthy returns and attractive yields
in the months ahead, as the market recognizes the value of these quality
investments.

Looking ahead for the Select Portfolios, our focus will continue to be on
supporting the stability of the portfolios' income streams, especially if we
remain in a lower interest rate environment. Beginning in 2001, many of the
bonds in the Select Portfolios will become callable by their issuers. If
interest rates remain lower than they were when the portfolios were assembled in
1992, our goal will be to pre-empt some of these calls by selling bonds prior to
their call dates and replacing them with high-quality bonds offering attractive
yields. Nuveen's expertise as an experienced investment manager knowledgeable
about the unique aspects of the municipal bond market is key to our ability to
select the right securities for our portfolios and add value for our investors.

1. General Information and Significant Accounting Policies
The Trusts covered in this report and their corresponding New York Stock
Exchange symbols are Nuveen Select Tax-Free Income Portfolio (NXP), Nuveen
Select Tax-Free Income Portfolio 2 (NXQ), Nuveen Select Tax-Free Income 
Portfolio 3 (NXR), Nuveen Insured California Select Tax-Free Income Portfolio 
(NXC) and Nuveen Insured New York Select Tax-Free Income Portfolio (NXN).

The Trusts are registered under the Investment Company Act of 1940 as
closed-end, diversified management investment companies.

The Trusts' investment adviser, Nuveen Institutional Advisory Corp. ( the
"Adviser"), a wholly owned subsidiary of The John Nuveen Company, administers
the investments and maintains ongoing surveillance of such investments to insure
that they continue to meet the Trusts' investment objectives and credit quality
standards. The Adviser does not intend to adjust the portfolios except 1) to
invest interest payments on municipal obligations that are not currently needed
to pay dividends or expenses; 2) to reinvest principal payments on municipal
obligations resulting from their maturity or early redemption; 3) to sell
municipal obligations when the Adviser believes that continuing to hold them
would be inconsistent with maintaining the Trusts' high credit quality, and to
reinvest the proceeds of such sales; and 4) for certain other purposes.

The Trusts intend to liquidate all of their assets no later than the year 2017,
unless extended, making a single liquidating distribution to shareholders at
that time. Any extension of these dates may be made only by an amendment to each
Trust's declaration of Trust approved by the Board of Trustees and by
the shareholders.

The following is a summary of significant accounting policies followed by the
Trusts in the preparation of their financial statements in accordance with
generally accepted accounting principles.

Securities Valuation
The prices of municipal bonds in each investment portfolio are provided by a
pricing service approved by the Trust's Board of Trustees. When price quotes are
not readily available (which is usually the case for municipal securities), the
pricing service establishes fair market value based on yields or prices of
municipal bonds of comparable quality, type of issue, coupon, maturity and
rating, indications of value from securities dealers and general market
conditions. Temporary investments in securities that have variable rate and
demand features qualifying them as short-term securities are valued at amortized
cost, which approximates market value.

Securities Transactions
Securities transactions are recorded on a trade-date basis. Realized gains and
losses from such transactions are determined on the specific identification
method. Securities purchased or sold on a when-issued or delayed delivery basis
may have extended settlement periods. The securities so purchased are subject to
market fluctuation during this period. The Funds have instructed the custodian
to segregate assets in a separate account with a current value at least equal to
the amount of the when-issued and delayed delivery purchase commitments. At
September 30, 1998, there were no such outstanding purchase commitments in any
of the Trusts.

Investment Income
Interest income is determined on the basis of interest accrued, adjusted for
amortization of premiums and accretion of discounts on long-term debt securities
when required for federal income tax purposes.

Income Taxes
Each Trust is a separate taxpayer for federal income tax purposes. Each Trust
intends to comply with the requirements of the Internal Revenue Code applicable
to regulated investment companies and to distribute all of its tax-exempt net
investment income, in addition to any significant amounts of net realized
capital gains and/or market discount realized from investment transactions. In
light of the Adviser's intention not to adjust the Trusts' investments except
under limited conditions, it is expected that the Trusts will generally realize
minimal, if any, amounts of both net realized capital gains and market discount.
The Trusts intend to retain such minimal amounts and, therefore, will record a
provision for federal income taxes on the amounts retained. To the extent more
significant amounts of net capital gains are realized, the Trusts may elect to
distribute such amounts to shareholders and no federal income tax provision on
these amounts will then be required.

Furthermore, each Trust intends to satisfy conditions which will enable interest
from municipal securities, which is exempt from regular federal income tax for
all Trusts and exempt from California state income taxes for Insured California
Select Tax-Free and from New York state income taxes for Insured New York Select
Tax-Free, to retain such tax-exempt status when distributed to shareholders of
the Trusts.
<PAGE>
Dividends and Distributions to Shareholders
Tax-exempt net investment income is declared as a dividend monthly and payment
is made or reinvestment is credited to shareholder accounts on the first
business day after month end. Net realized capital gains and/or market discount
from investment transactions, if any, are distributed to shareholders not less
frequently than annually. Furthermore, capital gains are distributed only to the
extent they exceed available capital loss carryforwards.

Distributions to shareholders of tax-exempt net investment income, net realized
capital gains and/or market discount are recorded on the ex-dividend date. The
amount and timing of distributions are determined in accordance with federal
income tax regulations, which may differ from generally accepted accounting
principles. Accordingly, temporary over-distributions as a result of these
differences may occur and will be classified as either distributions in excess
of net investment income, distributions in excess of net realized gains and/or
distributions in excess of net ordinary taxable income from investment
transactions, where applicable.

Insurance
Insured California Select Tax-Free and Insured New York Select Tax-Free invest
in municipal securities which are either covered by insurance or are backed by
an escrow or trust account containing sufficient U.S. government or U.S.
government agency securities, both of which ensure the timely payment of
principal and interest. Each insured municipal security is covered by Original
Issue Insurance, Secondary Market Insurance or Portfolio Insurance. Such
insurance does not guarantee the market value of the municipal securities or the
value of the Trusts' shares. Original Issue Insurance and Secondary Market
Insurance remain in effect as long as the municipal securities covered thereby
remain outstanding and the insurer remains in business, regardless of whether
the Trusts ultimately dispose of such municipal securities. Consequently, the
market value of the municipal securities covered by Original Issue Insurance or
Secondary Market Insurance may reflect value attributable to the insurance.
Portfolio Insurance is effective only while the municipal securities are held by
the Trust. Accordingly, neither the prices used in determining the market value
of the underlying municipal securities nor the net asset value of the Trusts'
shares include value, if any, attributable to the Portfolio Insurance. Each
policy of the Portfolio Insurance does, however, give the Trusts the right to
obtain permanent insurance with respect to the municipal security covered by the
Portfolio Insurance policy at the time of its sale.

Derivative Financial Instruments
The Trusts are not authorized to invest in derivative financial instruments.

Use of Estimates
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 at the date of the
financial statements and the reported amounts of increases and decreases in net
assets from operations during the reporting period. Actual results may differ
from these estimates.

2. Trust Shares
There were no share transactions during the six months ended September 30, 1998,
nor during the fiscal year ended March 31, 1998, in any of the Trusts.

3. Distributions to Shareholders
The Trusts declared Common share dividend distributions from their tax-exempt
net investment income which were paid November 2, 1998, to shareholders of
record on October 15, 1998, as follows:

Certain long-term and intermediate-term investments owned by the Trusts are
covered by insurance issued by several private insurers or are backed by an
escrow or trust containing U.S. government or U.S. government agency securities,
either of which ensure the timely payment of principal and interest in the event
of default (51% for Select Tax-Free, 59% for Select Tax-Free 2, 42% for Select
Tax-Free 3, 100% for Insured California Select Tax-Free, and 100% for Insured
New York Select Tax-Free). Such insurance or escrow, however, does not guarantee
the market value of the municipal securities or the value of any of the Trusts'
shares.

All of the temporary investments in short-term municipal securities have credit
enhancements (letters of credit, guarantees or insurance) issued by third party
domestic or foreign banks or other institutions.

For additional information regarding each investment security, refer to the
Portfolio of Investments of each Trust.

Successful investors know that a well-diversified portfolio - one that balances
different types of investments, levels of risk and tax management - can be the
foundation for building and sustaining wealth. That's why Nuveen offers you and
your financial adviser a wide range of quality investments that can help you
build a better portfolio in the pursuit of your financial goals

Exchange-Traded Funds

investment-grade quality municipal bonds. The fund shares are listed and traded
on the New York and American stock exchanges. Exchange-traded funds provide the
investment convenience, price visibility and liquidity of common stocks.

Nuveen MuniPreferred offers investors a AAA rated investment with an attractive
tax-free yield for the cash reserves portion of an investment portfolio.
MuniPreferred shares are backed 2-to-1 by the long-term portfolios of Nuveen
dual-class exchange-traded funds and are available for national as well as a
wide variety of state-specific portfolios.

Year 2000
The concern that computer systems may have problems processing date-related
information in the year 2000 and beyond has challenged businesses and
organizations to thoroughly review all aspects of their operations. We have
undertaken just such an approach at Nuveen in preparation for the millennium.
Over the last 10 years, our trading, fund management and pricing systems at
Nuveen - the systems that directly affect our investors and their financial
advisers - have been updated or replaced to address the Year 2000 concerns.

We continue to work closely with our transfer agent, custodian and other service
partners to monitor readiness and address other remaining systems issues. Our
initial testing indicates we are on schedule, and we have targeted year-end 1998
to complete verification of vendor compliance and service partner readiness.
However, we can give no complete assurance at this time that the steps we have
taken will be sufficient to prevent any problems that would impact the Nuveen
Exchange-Traded Funds.

Each Portfolio intends to repurchase shares of its own common stock in the
future at such times and in such amounts as is deemed advisable. No shares were
repurchased during the six-month period ended September 30, 1998. Any future
repurchases will be reported to shareholders in the next annual or semiannual
report.
