If you missed the Shubert Alley Flea Market early in the fall but still hanker for theatre memorabilia, the place to be, Jan. 11, is the New York Public Library for the Performing Arts. That's the big day for the 25th Annual Performing Arts Bazaar -- the last one this century! Theatre lovers won't want to miss this opportunity to purchase rare books, signed posters, autographs, photographs, records and vocal scores. Special offerings include a signed (and kissed) Full Gallop poster, courtesy of actress Mary Louise Wilson, bound copies of "Theatre" magazine from the early 1900s, theatre and opera programs dating back to the 19th century, and an entire gallery of lp recordings.

Admission is $5 at the door. For information on this one-day event at 40 Lincoln Center Plaza, 10:30-4 PM, please call (212) 870-1670. Please note that cash and checks are the only method of payment; please bring credit card I.D. for purchases over $100.

As for the branch's upcoming renovation, work is scheduled to begin in July and expected to take two years. According to spokesperson Alex Wang (Dec. 18), "Most of the library materials will be available at interim spaces, such as the mid-Manhattan library and an annex on Manhattan's midtown west side." Wang also assured Lincoln Center theatregoers the construction work would take into account the schedules at the next-door Mitzi Newhouse and Vivian Beaumont Theatres -- both of which were renovated themselves only a year ago. Expected library enhancements include new reading rooms, new wiring for databases and laptops, improved exhibition galleries, and a new information/welcome center.
