Because the editors of this project are in America, you should assume that releases are American unless otherwise indicated. The years noted are the original date of release; a second date follows a "+" when the same label issued the same record with some significant change in content. Non-US reissues are noted only when there is some content variation or there is no other version available.
Discographies in no way differentiate between records that are in print and impossibly rare; this is a critical guide, not a catalogue.
Records are marked as EPs if they contain four to six songs. But there are exceptions: a 7-inch with more than six songs will also be designated an EP, a full-length album (roughly 40 minutes, but nobody's counting) with six or less songs will not. A record of more than six songs, in which multiple mixes of a song account for the excess of tracks, is still an EP. Although there's no logical excuse for it, some significant releases of only three songs (especially when the record has an actual title) have been listed as EPs; such deviations are noted in the text.
Titles that appear within quotation marks designate singles, which are listed and mentioned only in cases of special significance. This stylistic convention necessitates the omission of quotation marks from titles that appear with them on record covers. Generally, idiosyncratic type case conventions (and needless punctuation marks) in band names, titles and labels have been respected when there seems to be both consistency and general acceptance for such use.
