There are several resources online that list album credits. They populate their databases right off of the album artwork that is submitted. Generally, they do not accept changes or anything that is not physically printed on the artwork of the album. The two main places I've found online are allmusic.com and albumcredits.com. Established in 1991, the All Music Guide (AMG) has been the definitive source for information about the quickly expanding music market. By 1995, allmusic.com was launched and has been the place for 'music fans to indulge their passion.' Recently, AlbumCredits.com has come on the scene and has grown quickly. It is from the same database as the All Music Guide, but the people credited can claim their profiles and enter contact info. Although still in beta, when the site goes to the '1.0' version there will be a paid option to add functionality to your profile.
