Information history may refer to the history of each of the categories listed below (or to combinations of them). It should be recognized that the understanding of, for example, libraries as information systems only goes back to about 1950. The application of the term information for earlier systems or societies is a retronym.

Heting Chu (2010) classified the history and development of information representation and retrieval (IRR) in four phases. "The history of IRR is not long. A retrospective look at the field identifies increased demand, rapid growth, the demystification phase, and the networked era as the four major stages IRR has experienced in its development:"

  1. Increased Demand (1940s–early 1950s) (Information explosion)
  2. Rapid Growth (1950s–1980s) (the emergence of computers and systems such as Dialog (online database))
  3. Demystification Phase (1980s–1990s) (systems developed for end-user searching)
  4. The Networked Era (1990s–Present) (search engines such as AltaVista and Google)
