- Spread Magazine
- Prostitutes of New York (PONY). The information here looks very old, but apparently was still up-to-date as of October 2007, judging by this press release. There's also a PONY website, last updated 2003.
- Sex Worker’s Outreach Project NYC (SWOP-NYC) (information about meetings here
- Sex Workers Outreach Project (SWOP) East ( and its blog
- Sex Workers Outreach Project - USA (site includes page about International Day to End Violence Against Sex Workers, including international list of organizations)
- The Sex Workers Project (and page about it on the website of the Urban Justice Center)
- Desiree Alliance (main page includes list of blogs)
- What About Kristen? - press release with contact info for various groups, as of March 11, 2008 (another copy here)
- Sex Workers Internet Radio Library (SWIRL)
None of these groups seem to be holding any events in the near future, other than regular public meetings of SWOP-NYC.
P.S. (May 16, 2009): I just now learned of the existence of a new Meetup group, Savvy Sex, which is concerned about a variety of issues including the rights of sex workers.
