What to do with all the tall picture books we have!

[pandapickle]

Any ideas on what to do with all the very tall pictures books we seem to have? I have a pile of at least 20 that don't fit on bookshelves. I've been storing them horizontally but it doesn't look terribly tidy,,,

Put them in a basket to be flicked through front to back, like records. This kind of idea, but you can reproduce it with any floor standing storage box that's sturdy, heavy-ish and not too deep like this

Or a sling bookcase such as tidybooks - they hold more than you'd think - or IKEA spice racks (bekram?) attached to the wall.

Magazine rack?

I have a tidybooks bookcase it's very handy!
