Thanks for the comments, and the storage tip! Luckily I didn't have them stacked that way for long- it only took one day of being frustrated that I couldn't easily flip through them that I pulled them out and started using it to store my cassettes/tape player, cd books, and my old ticket stub covered laptop. I think it's a great way of organizing the rest of my music media- but wasn't sure what to do about my records and player...

...until I was walking my dog past the school across the street this morning and they had this shelving unit next to the dumpster! Woo! It's completely perfect for storing my whole collection of records (not just the portion that I could fit in the shelf before) with them stacked vertically! Can't wait to get it refinished and find a spot for it.
