LOL! I just stumbled across this after reading about version 1.0 of the WINE project being released.
The WT Library is right at the bottom of the top 10 Platinum list!
An electronic version of some of the Watchtower society's publications released from 1970 (english; span vaires between the languages) to date; comes with an extremely good search-tool. Windows is the currently (2005) sole supported platform. Currently distributed only to baptized Jehovah's witnesses. Distributed in quite some languages, but program functions are believed to be identical for all of them. Menus, data and hotkeys vary between languages.
Here's a wiki on how to install it:
