I use IKEA "bonde" bookcases with the glass doors & these look very nice. They are 56" or so and each single bookcase can hold four rows of records. They are about 15" deep, which I find is ideal as it also allows me to use dividers to seperate the records. As they are modular & have been an IKEA staple for a while now, hopefully they will be around in the future for expansion.
Hope this helps
