Q. In need a book on the Japanese internment camps in the U.S. during WW II.

In the Library's catalog try a keyword search for internment or Executive Order 9066, we have a few volumes that come up. 

If you know them, you could also try a search on individual internment camps (e.g. Manzanar is one of better known ones). Start at Wikipedia and read the article on internment camps and find other keywords and location names with which you could search the catalog.
