I wouldn't know how to start as I collect all different genres; NS, MS DS, SS, gospel, blues, funk, disco, Motown, Stax, Cleveland labels ....
.... I also collect UK / US / foreign releases from around 25 other countries ....
.... so I wouldn't go with alphabetical or by genre .... no idea where I'd start ... PLUS there's all the 12"ers, LP's, CD's ... I'll leave it till next year again) .....
... just to finish, another one of my wooden boxes, a big brute that I keep some of my picture sleeve 7"s in ... too big to lug about much though ...
