Awwwww, my site isn't in the list
http://btengineer.blogspot.com For the Blog, which has links to the encyclopedia with recordsheets (BT and QS) for all mechs (and data, though sometimes it doesn't display, for all 5222 canon BT units, 13 from battletechnology, and soon 240 from fan based TRO 3063).
I finished the RS for all CV/Fighters, but need to do a big code update on the site (<30 days) so that all the RS will be PDFs instead of PNGs.
I should have dropships, jumpships, warships, stations, mobile structures, buildings, etc, all working within a month or two as well. Soon after I'll have support for tracking your units (think virtual record sheet) instead of using paper record sheets for your games.
If you go through history I've put up all sorts of things, even a 200mb file with quick strike sheets for every canon design in the game.
