The sole purpose of "The Archive" is an index, nay, a database of information that is stored for retrieval by Will Carter. It is crucial to the existance of Will Carter's memory because without The Archive countless people would be forgotten and probably insulted through their being forgotten. The Archive enables Will to find useful information long forgotten by most. It is like the Diary of Tom Riddle--a gateway to the past, to a persona that existed only in the moment of its creation. The Archive consists, currently (Mid 2006), of over 800,000 articles, documents, and transcripts, many of which might come of some use. Will is apparently a bit of a pack-rat in terms of storing data.
Will is able to access any part of The Archive very efficiently and dig up information dating back to his entrance to the internet.
