How To Store Record Collection?

I am very happy with the racks from Music Direct. They have two styles, the one in the picture, and the Cherry wood with black supports, which what I have. (I like both styles, but my wife really wanted the cherry, as it went with the decor better. I don't mind, as long as I get my racks! They are expandable too, so if you collection keeps growing, so can they!)

Music Direct LP Racks

They are not only very aesthetically pleasing (i.e. high WAF!), but they go togather quickly, easily and work great.
(They have the back stop to keep your records lined up nicely too!)

My two cents worth anyway.

IKEA Bonde or Expedit shelves are excellent for record storage. Both come in various sizes.

I have used Per Madsen's record racks for years with excellent results and out standing customer service from him. Check them out at:

Ikea Effektiv storage modules work great for us. Effektiv is a modular system you can build as high and wide as your space allows. It's more expensive than Bonde or Expedit, but the modularity makes it adaptable to difficult spaces.

I second the Pers Madsen record rack suggestion. I have used them for a number of years and have about 5,000 LPs stored in them. They have a very high WAF. Very flexible as to how you design your storage space. Easy to expand. Moving them with the LPs inside is quite easy and much more convenient than having to take the LPs off of the shelf, move the shelf and then put the LPs back on the shelf.
