BOSTON INTERNATIONAL ANTIQUARIAN BOOK FAIR

Book collectors are a queer breed, and for most of them this annual event, which has been taking place for three decades, is trouble — it’s like a crack house for bibliophiles. It’s also a virtual museum of rare documents and ephemera: among the stuff up for grabs is a letter from Thomas Jefferson and an original unpublished composition by Leonard Bernstein. It’s at Hynes Convention Center, 900 Boylston St, Boston | October 28-30 | $8-$15 | http://www.bostonbookfair.com/.
