Paris may have had its Sylvia Beach, but New York was lucky enough to have Frances Steloff. She opened Gotham Book Mart in 1920, and quickly became a defender of the First Amendment rights of authors. She championed such once-banned works as Henry Miller's Tropic of Cancer, and numbered among her admirers Ezra Pound, Saul Bellow, and Jackie Kennedy Onassis. Frances has since passed on, but her aura lives. As always, the emphasis is on poetry, literature, and the arts. This is New York's undisputed literary landmark; look for the sign that says WISE MEN FISH HERE. Note: The store is scheduled to move sometime in the near future, but the location and date were unknown at press time; call before you go.
