Anna, and others visiting Manhattan looking for miniature books, should pay a
visit to Printed Matter at 77 Wooster Street (in SoHo). They specialize in
artist books (in editions over 100 copies) and independent press
publications. They have shelves and shelves of non-miniature books, but
check out the glass cases for an interesting selection of unusual miniature
books that are often surprisingly inexpensive. In the past I've gotten
catalogs from Printed Matter and they still may send them out. Their phone
number is (212) 925-0325.
