An NPR piece from July 8, 2010, Stanford Ushers In The Age Of Bookless Libraries, continues the e-book conversation.

Library chief Helen Josephine says that in the past five years, most engineering periodicals have been moved online, making their print versions pretty obsolete — and books aren’t doing much better. . . . The new library is set to open in August with 10,000 engineering books on the shelves — a decrease of more than 85 percent from the old library. Stanford library director Michael Keller says the librarians determined which books to keep on the shelf by looking at how frequently a book was checked out. They found that the vast majority of the collection hadn’t been taken off the shelf in five years.
