Visit a book arts gallery or collection in your community. You can find some at The Center for the Book Arts in New York, the Arts of the Book Collection at Yale University and the Book Arts and Special Collections Center at the San Francisco Public Library. You can find more places where artists' books are displayed for the public.
Contact an artist book seller or attend a show. Information about events can be found at the following websites: Philobiblon, Colophonbookarts and SFCB.org. Granary Books maintains a searchable database of books.
Take care in handling the books. Use latex gloves, and take the time to carefully open, unfold and handle the books. Follow any rules of the gallery or collection in handling these sensitive objects.
