So after spending the better part of a week looking for a near-mint copy of The Rolling Stones' Got Live If You Want It, I was flipping through some unsorted vinyl and discovered that I already own a mint copy of the album! That was enough to convince me it was time to create a spreadsheet for my vinyl collection. Remembering what I currently own, as opposed to what I once owned but got rid of when I foolishly decided that CDs were the only form of music I'd ever want, was proving entirely too complicated.
Other discoveries that came about as a result of the spreadsheet: (1) I apparently own every Josie Cotten and Comateens album ever released; (2) I actually purchased an Ebn Ozn album at some point; (3) Jan and Dean Meet Batman is still the dopiest album I've ever purchased.
The spreadsheet is only about 90% complete at this point, but I should wrap it up tomorrow or the next day. It's interesting to see how many albums I own in multiple editions--in some cases, it's the mono and stereo version of the same album (the first 9 Beatles albums, for instance), in other cases it's a different cover (the UK and US versions of Blind Faith), but in a few cases it's because I didn't remember having an album so I bought it again. *sigh*
