"Brooklyn is an artist-run, nonprofit organization headquartered in Brooklyn, New York. Our mission is to promote artist books as an art form and educational resource; to provide educational institutions and the public with programming involving contemporary artist books; and to assist artists in exhibiting, distributing, and publishing innovative bookwork."
So this is a fantastic website. Reed has created this hub for their artists' books collection. They've digitized many books, so you can look at books page by page. If you do enough clicking and searching to get to the individual pages, you can zoom in really far on the pages. All in all, a great artists' books resource.
How to get to the place where you zoom in:
Click on the book you want to see. On this page you can watch a slide show of someone going through the book. They even start with taking the book out of its case/box. However, if you want to see individual pages zoomed in, you can click the "view in context" button next to the title of the book that is located below the slide show. Not all of the books have this option, but many do.
"An online repository of facsimiles, metadata, and criticism... ABsOnline consists of files that display artists' books, exhibits, essays, and links to other collections or resource materials for this field."
What I found really cool about this site is when you view a book, there is a really comprehensive profile on the right side of the page that besides providing you with the artist and publication history, also includes an 'aesthetic profile' and other comments and tidbits.
