Library patrons may not know how to use a library effectively. This can be due to lack of early exposure,

shyness, or anxiety and fear of displaying ignorance. In United States public libraries, beginning in the 19th century these problems drove the emergence of the library instruction movement, which advocated library user education. One of the early leaders was John Cotton Dana. The basic form of library instruction is generally known as information literacy.

Libraries inform their users of what materials are available in their collections and how to access that information. Before the computer age, this was accomplished by the card catalog — a cabinet containing many drawers filled with index cards that identified books and other materials. In a large library, the card catalog often filled a large room. The emergence of the Internet, however, has led to the adoption of electronic catalog databases (often referred to as "webcats" or as OPACs, for "online public access catalog"), which allow users to search the library's holdings from any location with Internet access. This style of catalog maintenance is compatible with new types of libraries, such as digital libraries and distributed libraries, as well as older libraries that have been retrofitted.
