How to make a bookcase you can move with the books IN it.

I recently put together Yet Another Bookcase, and this time I kinda-sorta documented it. I got a pic taken of me "holding" it, and wrote how to make one. I make these to be efficient, "high density" storage, so the octavos (regular size hardback and trade paperback) get their own bookcase and and quartos (larger size, often picture books, and magazines and catalogs) get a slightly different design (described but not photographed).

Here's the blogpost on the local hackerspace/makerspace blog:

I've written about these bookcases before, such as here:
