The Saga of the Manga Bin
I accumulate manga. As one series can go into 20 books, storage is a big problem of course. My bookshelves were crowded, so I went to the manga bin. How it looked at first:

Mostly, I threw manga I had read into this plastic tub. It kept the manga mostly corralled, but some pages were folded and it was hard to find the exact volume I wanted.

It took me 30 minutes to clean out the manga bin to create the above neater manga bin. It has less storage, but it is easier to view the titles.
