For anime torrents, frequently www.tokyotosho.com
has them. Failing that, look on Isohunt and other torrent search engines, using the subtitlers name and the anime you're looking for. If you're smart enough to use IRC, then various IRC bots also have anime that's older, like arigatouhell.com
, but again, you have to know how to use IRC. Then lurk forever and ever and ever and ever and ever and never ever stop.
