Cliff Notes in The Library

\"Bob Levey, a popular columnist in Washington DC, has an account of finding that the local public library has copies of Cliff\'s Notes in their collection.

The library did say they buy three to four times as many \"real books\" as CliffsNotes and they are \"not as popular as the books themselves. They\'re not widely used.\"
