Bush, Vannevar. "As We May Think." The Atlantic, July 2945, pp. 112-124.
Vannevar Bush publishes "As We May Think" in The Atlantic. Bush proposes a device he calls the Memex, which would store content on microfilm. Each frame of microfilm could be tagged, and the Memex could use those tags to index and cross-reference all of the content. Each user would be able to create their own web of links and annotations.
