The Science and Ethics of Genetic Engineering. This is the call number . We use call numbers to organize and shelve items in the library. Most of our older periodicals, those published more than 3-6 months ago, are bound together with hard covers. Our bound periodicals are assigned call numbers, just like books.
Call numbers have two parts.
Start with the top line, the Subject Number. Now look at the second line, the Book Number. It distinguishes different books on the same subject. Ask at the Reference Desk for help if you have trouble finding a book or journal.
