I don't mean to criticize, so please don't take it that way, but OLP doesn't really have any "b-sides" per se. A "b-side" is a song on a single other than the song being marketed. For example, if they release(d) a Made of Steal single and OTiF was on it as well, OTiF would be a b-side. A b-side is not merely a "rareity" which is, I think, what you are looking for. The term "b-side" originated when singles were released on media with 2 sides (ie. vinal record or cassette tape). They would always put the single they were marketing on the a-side and the b-side, well...you can guess where that would go
Anyway, if you're refering to "rareities", this list is from Rich and Shelly's site...
