Storing softbound books

What's the best way to store sotfbound books? I don't mean paperbacks, but really softbound books like poetry chapbooks and the like. Storing them upright is kinda out of the question, was wondering if there's anything wrong with just laying them on the side?

>1 filox: Why is storing them upright out of the question? The few books of the type you describe in my library are all stored upright on a bookshelf between taller hardbacks or slipcased books.

>2 kdweber:
Same here. I have a number of card-bound chapbooks from Incline Press et al., that share the shelves upright with weightier tomes.

>2 kdweber: I guess if I put them between other hardbacks it would work, I was thinking more if it's on a shelf alone (e.g., starting to fill in a new shelf). They don't stand so well upright on their own.

Another alternative would be clamshell boxes.

Or possibly those diagonal-faced half-boxes for shelving periodicals.

>1 filox: We store ours in acid-free envelopes. Some are slipped between hard-cover books on the shelves; others are in magazine boxes.

>1 filox: you might also be curious to see the solutions hobbyists have come up with for “zine” storage, as zines are basically the modern popular incarnation of chapbooks.
