Libraries use classification systems to organize the books on the shelves. A classification system uses letters and/or numbers (call numbers) to arrange the books so that books on the same topic are together. This arrangement assists in “subject browsing:” you find one book in the catalog, go to the shelf, and an even better book is sitting right next to it.
