The games and original sites for each prior Spring Thing can be browsed here.
The IF Wiki also maintains a page on Spring Thing, and the IFDB Spring Thing tag catalogues most of the games that have been entered over the years. The games are also preserved at the Interactive Fiction Archive.
Spring Thing was first announced by Adam Cadre in 2001. The first competition took place in spring 2002. Cadre ran the competition for two years.
After a year of inactivity in 2004, Greg Boettcher revived the competition and organized it from 2005 to 2013, during which time it became a regular mainstay in the parser IF community.
Aaron A. Reed took over managing the competition in 2014, during a period where communities making non-parser games began to discover the Thing. For the 2015 season, he re-branded it as a “festival.”
IF Author Brian Rushton (MathBrush) wrote a year-by-year history of Spring Thing from its inception through 2017.
