In the last year or so a great number of "market listings" have become available online. Each has its own strengths and weaknesses--which is why we include a wide variety here. Let this help you make decisions about where to send your writing.

Spicy Green Iguana
http://www.spicygreeniguana.com/index2.html

SGI is run by writer/editor and college student Matt Hayes and has expanded considerably since it started several years ago.. His lists don't include response times with the listings, but he's working on it. The site also carries reviews. Updated monthly as Matt gets time.

Stef and Paula's List
http://home.att.net/~P.Fleming/Sfmarket.html

Very straightforward newsgroup-style list of speculative fiction markets Includes response times, and is updated quarterly.

Tangent Online
http://www.tangentonline.com/

Tangent is a labor of love by our friend Dave Truesdale. It's the ONLY magazine that reviews the short fiction markets regularly (an ambitious undertaking!) and the online version has a great links list. No one is closer to the market than Dave!

The Market List
http://www.marketlist.com/

An ambitious project by Chris Holliday to provide genre writers of short fiction with a quick reference guide of current market information. Is updated only sporadically, but has a searchable index and a downloadable version you can put on your desktop.

The Write Market
http://www.writemarket.com/

Christopher Reynaga, another college student/writer/editor, has put up the Write Market to serve as a resource for fellow writers. His market listings are scattered, but often include guidelines and notes about his personal experiences submitting to them.
