I don't have a room for my comics, most of them (single issues anyway) are on shelves in the basement. (Well away from any water source mind you...) What is odd about my collection is that I don't use comic bags. Instead I use binders and acid free page covers. Golden and Silver Age all get boards, only certain (usually more valuable) bronze-modern books have them. The binders kind of serve the same purpose and take up less space.

A couple of general shelf pictures from a while ago. I started out hand labeling the binders with masking tape and eventually switched to a label maker.

Most books are sorted by title. Series that are too short (mini-series, specials, or ones I don't otherwise collect) are usually combined into "group binders." For instance, I have "Misc. DC," "Misc. Marvel," "Misc. Charlton," "Misc. Golden Age," "Superman Related," "Justice League Related," etc. I also keep a cache of unread books (which are a respectable collection unto themselves). So if I have a whim to read, say Fantastic Four, or something from the Silver Age, I just pull one out.

Then there are some series where I've been working on complete runs before I start reading them. Legion of Super-Heroes was one such book. I always liked the Legion, but hadn't really planned on collecting it. Then I started seeing a lot of them in quarter and fifty cent bins, and pretty soon had a pretty good collection going. After a period of buying them and then not reading them and noticing that my collection was getting pretty complete, I decided to start reading them in order from the point where the book splits from Superboy, filling in gaps with Lone Star. These were my unread LSH books a year or two ago, the collection has grown quite a bit since then.
