The first episode of Smallville aired on October 16, 2001, and people began writing fanfiction, including slash, immediately. Livia designed the look of the archive, Naomi provided the scripts that allow people to archive their own stories, Calysta Rose set up and installed them, and Minotaur generously hosted the archive at slashdom.net. The Smallville Slash Archive went live on October 20, 2001.
With Minotaur’s passing in 2009, the archive’s continued existence and maintenance became problematical. In an effort to preserve the thousands of stories in the SSA, the archive was imported to the AO3 through the Open Doors Project : Smallville Slash Archive.
