Ideas for something to hold LPs ??

If you have any IKEA store next to you, they have book-shelf racks that are realy designed to hold vinyls. Nicely finished and having square cells all arround that are exactly 12" X 12" X 12"! I've got it last year without paying extra for the brand names (only $175) and I'm holding there my collection of 650 vinyls.
If you cannot find it in IKEA I believe that the HOME DEPOT has everything to build such rack. The idea is to place them in small groups standing vertically and organized by your taste. Placing them in small groups will prevent vinyl gatefolds from excessive tension when you're trying to grab your desired record.

Yes, IKEA is also a very good option. Their furniture design is improving all the time, and they're very affordable.

Abstract7, that's a very impressive looking system you have, and the LP rack is super cool. If it's not a problem I'd like to have a copy of your plans. Thanks!

I had one made that holds several hundred in a record store rack format; all LPs face forward and I flip through to find the one I want. The front of the cabinet is roughly 3/4s the height of an LP. The lid is hinged and completely covers the vinyl. I keep it fairly full of favorites and the construction prevents warping.

As a long-time LP owner (I've owned some of my 3000 LP's for more than 30 years), I've found that just about any storage device is fine, PROVIDED it keeps the LP's upright, and allows the LP's to be stored firmly next to each other, but not tightly. I use a pair of inexpensive book cases that work fine.

Bear in mind that vinyl is a viscous material that will, over an extended period, warp or slump at the edge if the LP is not kept upright, so be sure that your LP's do not lean away from the perpendicular, or get a curvature in the jacket. If there is room at the end of shelf, use a bookend or solid item to fill the space so the LP's don't lean over. Boxed sets are usually best stored lying flat, since there is usually enough room inside the box to let the LP's "slump" a bit.

For someone with a little bit of ambition with the end result a lot more self-satisfaction may I recommend that you:

Buy some veneered 3/4" plywood of your choice with 1/4" plywood veneer for the back of the case. Prices for cabinet grade plywood will vary from 50.00-90.00 for 3/4" and 30.00-65.00 for 1/4", depending on the area you live in. You will also need a few tools including a tape measure, a 7 1/4" power saw with a thin kerf panel blade, a straight edge and a hand plane. For trim on the case edges and shelves of the plywood you may want to add some round molding which you could order by the lineal foot or if you are really ambitious you might buy some solid stock of matching wood and a router and make your own.

In addition to the above you will need a fine grit sand paper, 220-320 and a few coats of finish. A satin or semi-gloss urethane is simple to apply and tough but for the more ambitious, a laquer or oil finish might be preferable and certainly more attractive.

I know this may sound like too much work for some but the end result is something custom made for your needs and in the process you save money and have the satisfaction of making it yourself. A bookcase/record cabinet is a quite simple beginner woodworking project. In the event you don't want to go the route of building it yourself you may consider a local cabinet maker/woodworker who could custom make it for you to fit your specific needs and space requirements at a nominal cost.
