Extensive reference, resources and information from all over the world. The site has undergone a welcome clean-up and update. bi.org remains the reference of all references for the traditional bisexual resources sites.

All in Dutch, seems active and rich in content.

All in German, seems active and rich in content.

The only national resource for Australia. Unfortunately, out of date for several years.

Last update: 2008.

The Bisexual Resource Center is a formally registered non-profit organization based in Boston, USA. They maintain a broad range of references and resources on their web site, although much of it reflects events and conferences of the past. It is nevertheless one of the few bisexual resources on the web today with relatively recent information.

The official site of the BiNet USA, the oldest national bisexual organization in the US. As interest in local and regional activism faded in the last decade, so did the national organization. BiNet USA is experiencing somewhat of a revival lately by shifting its focus on a broader pansexual and queer scope. Don't be discouraged to find to find bi-specific information, get past the main page and dig further into the site. Well worth visiting to learn about the history of bisexual activism in the US on their Bi History Timeline (no link on the main page, go to Bi Health first!).

The official site of the American Institute of Bisexuality, originally founded by Fritz Klein in 1998. Once a very active and frequently updated site with even free bisexual personal ads. You can still find a good description of the Klein Sexual Orientation Grid and an extensive bio of Dr. Fritz Klein. The remainder is mostly made up of links to other sites.
