equired to pay again to access something I previously paid for to access and read, or I might not even be able to pay for access without being a member. There are other differences too. Searching things I have collected myself is different than searching the vast Web, and both have their place. One author (Johnson, 2005) who has collected on his PC an archive of all his writings and notes plus a few For Peer Review thousand selections from books he has read over the past ten years is convinced that there are meaningful differences. He argues that there is “a fundamental difference between searching a universe of documents created by strangers and searching your own personal library.” Influenced by the Memex article, he adds that when you are “freewheeling through ideas that you yourself have collated” it is “uncannily like freewheeling through the corridors of your own memory.” And of course there is the matter of the physical connection. Despite all the advances in networking, wireless and otherwise, there will always be times and places in the foreseeable future where a person will simply not be able to establish a high-speed connection to the Internet, rendering the Memex as part of one’s own memory temporarily amnesiac. Further, for some applications, even when a high-speed connection at today’s rates is indeed available, it is not fast enough. Desktop Collections 2t-S-1Ed-D-P 21 John Wiley & Sons Page 22 of 38
Page 23 of 38 2t-S-1Ed-D-P The desktop, or personal computer, is closer to the Memex in that we have collections of digital and digitized material in a machine (or set of machines) that fit on a desktop. But it is not yet the unified type of environment portrayed in the Memex article. Most of the material is not coming into the system in a single format (although a lot of it might be acquired via the Web), and finding items on a personal computer with a lot of storage capacity has until recently often been slower than finding things on the Internet. For Peer Review Some researchers in this area are concentrating on the Memex’s inclusion of all of one’s books, records and communications, and have been working on ways not only to accumulate everything but also to be able to find items amidst all that. One of the most ambitious projects, for example, is Gordon Bell’s MyLifeBits, where he and a small team are attempting to store everything from Gordon Bell’s life, including books, articles, Web pages, photos, email, written correspondence, telephone conversations, radio and television, and just about anything else he looks at or hears (Bell, et al., 2004; MyLifeBits Project, 2005). The procedures for accumulating the information even include an automatic camera worn like a pendant on a necklace (or pinned like a brooch to one’s shirt or coat). Aside from the challenges in accumulating information from these varied inputs, the project is facing challenges in organizing, browsing, optionally annotating, and retrieving items from such a volume of disparate types, and especially for the non-traditional formats such as audio and video. There are also issues with extracting or creating metadata, and with ownership rights, particularly when information is accumulated as part of one’s work for an employer.
