Current wearable camera and computer technology opens the way for preservation of every printed, computer mediated and spoken word that an individual has ever seen or heard. Text images acquired autonomously at one frame per second by a 20 megapixel miniature camera and recorded speech, both with GPS tags, can be uploaded and stored permanently on available mobile or desktop devices. After culling redundant images and mosaicking fragments, the text can be transcribed, tagged, indexed and summarized. A combination of already developed methods of information retrieval, web science and cognitive computing will enable selective retrieval of the accumulated information. New issues are engendered by the potential advent of microcosms of personal information at a scale of about 1:1,000,000 of the World Wide Web.
