National Libraries Week

It's National Libraries Week.  Please remember first of all that BOOKS = KNOWLEDGE = POWER = (FORCE X DISTANCE) ÷ TIME and thereafter remember the three rules of the Librarians of Time and Space:

1. Silence
2. Books must be returned by the last date stamped
3. Do not interfere with the nature of causality

A good library is, after all, just a genteel black hole.

With infinite thanks to Terry Pratchett, creator of L-Space and more
