The Library 100

Library member organization OCLC has produced a list of the top 100 novels held by libraries around the world.  As their site says: "Yes, libraries offer access to trendy and popular books. But, they don’t keep them on the shelf if they’re not repeatedly requested by their communities over the years. We’ve identified 100 timeless, top novels—those found in thousands of libraries around the world—using WorldCat, the world’s largest database of library materials."  This page has book covers and links to libraries for these books. 

You can also go to the page for Librarians to download bookmarks with the logo and the list of books on the back--all 100 on a bookmark!  And look at the Frequently Asked Questions to find out more about how they identified this list of books.
