1. BiteNova (formerly known as “Bi-Torrents”, BiteNova is a free Torrent site with a spartan look and fast searching format.)

2. Isohunt.com
September, 2007: Isohunt is barring American users from connecting to American torrent trackers. American users, however, can still use Isohunt to find torrents, and connect to third party trackers.

3. Torrentscan.com (a "meta-search" engine, which is a search engine that searches other search engines)

4. Torrentspy.com March 24, 2008: Torrentspy has voluntarily closed its doors. Instead of conforming to the American court mandates to change their privacy policies, the Torrentspy team has opted instead to cease operations. A sad day for downloaders everywhere.

5. Torrentportal.com

6. Bitsoup Bitsoup is a growing favorite amongst P2P downloaders. As the trend towards private torrent sharing continues, you will need to signup and join as a member to participate in the Bitsoup swarm.

7. LegalTorrents.com (As the name implies, this is a database of public-domain content. Thanks to Anand S. for this URL.)

8. Snarf It! (born from previous Suprnova influences)

11. Torrentmatrix.com

12. Mininova.org has 190,000 torrents indexed as of April, 2007. Mininova is the successor to Suprnova, one of the original big torrent databases of the Web.

13. FileMP3.org

14. TorrentBytes.net

15. Torrentreactor.to (Torrentreactor has made a comeback from a hijacking and an uncooperative hosting service. They have moved to a different server setup and a Tonga country domain outside the USA. Read the details on their home page.)

16. Torrentbox.com FYI: like Isohunt, Torrentbox is being sued by the MPAA as of February 28, 2006. The days for this fine search engine may be numbered.

17. BTjunkie

18. TorrentTyphoon.com (a unique bittorrent meta-search engine that searches several of the most popular sites. Unfortunately, it does not do a good job categorizing the torrent files themselves)

19. Yotoshi.com

20. The Pirate Bay (Pirate Bay, by readership size, is the most popular torrent search site today. Pirate Bay has an immense database of 600,000+ torrents, the largest database at this time.)
(May 31, 2006: The Pirate Bay has been shut down by Swedish authorities. Details are available on the Pirate Bay home page.)
(June 2006: The Pirate Bay has restarted operations, now that the police have duplicated the PB hard drives for forensic purposes. Enjoy this database while it is still around, folks!)

21. FullDLS.com

22. TopTorrents (has been down intermittently the last few weeks for unknown reasons.)

23. Meganova.org

24. ByTorrents Meta Search

25. Torrent-damage.net

29. Torrentlocomotive (special thanks to Juan C. for this submission)

30. bittorrent.com (the official Torrent website by Bram Cohen, the designer of the Python BitTorrent format.)

31. Fenopy (formerly Bitoogle.com) (the 'original' bittorrent search engine, which has now morphed into a metasearch engine. The results from your Bitoogle searches will point to various other torrent search sites. This site has been redirected recently.)

32. BTbot.com (this site has been intimidated into listing fewer and fewer current torrents. The administrator was likely spooked by the recent wave of lawsuits against Isohunt and Pirate Bay)

33. Special mention: Torrents.co.uk (This British site has been slow to load lately)

34. Special mention: LokiTorrent.com (In a precedent-setting MPAA civil law suit, Loki has been shut down by court order as of Feb 10, 2005. To add insult to injury, the MPAA has left a trashy saber-rattling message at the lokitorrent home page in an attempt to intimidate other P2P users. P2P users everywhere are mourning the loss of this excellent service, and the MPAA is estranging even more Internet users with its heavy-handed campaign.)

35. Special mention: Commonbits.com (This new beta search site is dedicated to media on progressive political content: audio, video, photos, reports, transcripts and other files. This is a place for activists to share their message, and for people to learn about other political choices.)
