As you've learned, books can be great sources of information, and the DCCC Learning Commons provides a collection of print and electronic books for research.
You can find out what print books, e-books, DVDs, CDs, and other physical materials are at the Learning Commons by searching the online catalog. The word catalog comes from the old days when all of this information was stored on cards, which were kept in a card catalog. Some habits die hard.
