Search the DDN Library Book Catalog | About the book collection DDN Library owns about 2,000 volumes, of which about half are included in this electronic catalog. Please note the following rules: If you borrow a book, fill out a green check-out card at the library counter. Please put your phone extension on the card so we can call to harass you if needed. Although we don't set a limit for how long you can have a book, please use common sense and bring books back when you are not really using them.Some books are considered "quick-reference" books and are labeled "do not remove from the library." This means what it says. Photocopy the pages you need or ask permission to borrow for a brief time. |
