To slightly extend the above description, the consequence of L-Space is that all libraries and book stores are, in some way, connected. The librarian of Unseen University knows how to navigate this "multi-bookstore", and can hence reach any library in the multiverse simply by taking the right turns in the back alleys of his own library.

L-Space is also the name of a website dedicated to Terry Pratchett, mirrored all over the world. It can be found at, and contains limitless information.
