The
memex (a
portmanteau of "memory" and "index") is the name of the hypothetical
proto-hypertext system that
Vannevar Bush described in his 1945
The Atlantic Monthly article "
As We May Think". Bush envisioned the memex as a device in which individuals would compress and store all of their books, records, and communications, "mechanized so that it may be consulted with exceeding speed and flexibility." The memex would provide an "enlarged intimate supplement to one's memory". The concept of the memex influenced the development of early
hypertext systems (eventually leading to the creation of the
World Wide Web) and
personal knowledge base software. The hypothetical implementation depicted by Bush for the purpose of concrete illustration was based upon a document bookmark list of static
microfilm pages, and lacked a true hypertext system where parts of pages would have internal structure beyond the common textual format, so it's fair to say that early electronic hypertext systems were inspired by memex rather than modeled directly upon it.
