Torrent Search Engines
There are numerous torrent search engines where you can find whatever you want. However some of them are crawling with annoying adverts and so on. Also be aware of fake torrents - they are not very exceptional. Read comments under torrents, someone may have already downloaded it and posted whether it is good or bad torrent. Search engines allow the discovery of torrent files that are hosted and tracked on other sites; examples include Mininova, Torrentz, The Pirate Bay, Eztorrent and isoHunt. These sites allow the user to ask for content meeting specific criteria (such as containing a given word or phrase) and retrieve a list of links to torrent files matching those criteria.
Torrentz.com
Perhaps the most reliable searching server. It doesn't have its own torrent database, but searches on the other servers' databases instead - therefore it finds practically everything there is.
Newtorrents.info
A well-arranged server with new torrents, as the name says. The torrents on front page are updated daily, but you can also search for a bit older torrents. If a torrent is a fake or somehow bad, it is usually recognised fast and written in comments or even the torrent's name (for example the NUKED prefix).
isoHunt.com
Large and reliable search engine. With cross-referenced trackers statistics for all torrents indexed updated to the hour, this is the best P2P files search engine and community. Browse torrents directory and Zeitgeist for what's new and popular.
The Pirate Bay
In 2003 server started out as a tracker (on a tiny adsl connection in Mexico) mainly for Swedes. Today the servers operate in many countries and torrent users can be found wherever a tiny bit of internets can be found.
Mininova
Visitors of Mininova can anonymously upload torrents to this website, tracked by any BitTorrent tracker. Scrape data (amount of seeds/leechers) is collected a few times a day.
