Probably the most "official" list of songs commercially recorded by Steve is found at the Red Pajamas Records Company Store, which shows each album, along with a list of tunes on each recording.

However, an even more extensive listing of recordings, including some out of print compilations, is found at The Steve Goodman Discography, part of the Steve Goodman Scrapbook.  On that page, many songs are even linked to lyrics.

Lyrics to many of Steve's songs can also be accessed through GLAD -- the Goodman Lyric Archival Depository, another part of the Steve Goodman Scrapbook.  You'll also find chords for a few tunes.
