Call numbers are letter-number codes that appear on the spine of a book.
We use the Library of Congress classification system of call numbers in our library, as do most research libraries. A call number is an address telling where a particular book is shelved in the library system. Call numbers for non-fiction works, magazines, and journals are symbols for subject matter. For instance, BF stands for psychology, QH for biology, PS for American literature, and so on. Since, also, a call number determines a particular item's location in the library system, this means that books on the same or closely related topics will tend to be shelved with one another.
