Library use

Many potential library patrons nevertheless do 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. These problems drove the emergence of the library instruction movement, which advocates library user education. Library instruction has been practiced in the U.S. since the 19th century. One of the early leaders was John Cotton Dana. The basic form of library instruction is generally known as information literacy.

Libraries inform the public 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. Electronic catalog databases are disfavored by some who believe that the old card catalog system was both easier to navigate and allowed retention of information, by writing directly on the cards, that is lost in the electronic systems. This argument is analogous to the debate over paper books and e-books. While they have been accused of precipitously throwing out valuable information in card catalogs, most modern libraries have nonetheless made the movement to electronic catalog databases.
