Is the World-Wide Web a library? Before starting the Masters of Library and Information Science program at the University of Washington, I would have agreed that it is. Now I am in the other camp, because one of the most important aspects of a library is the collection. A collection is not just a bunch of stuff; it is a conscious inclusion and exclusion of materials. The WWW, which has no controls on the amount or quality of its contents, can therefore not be a library.
Can a website be a library? I like the metaphor of the L-Space Web, which is that a website is the "real-life" incarnation of "Library-Space," the combined (and connected) space of all libraries and some special bookshops. My website is one little library which contains links to other libraries.
If only science were as reasonable as fiction.
