We just moved into a new home... the house is great except that we have tons of books and needed more book storage, but along with all the expenses of moving and moving into a new place and putting in a yard and all of that... we didn't want to spend an arm and a leg on bookshelves.  These were perfect.  Inexpensive, attractive and able to hold most of the rest of our books. They seem sturdy and were easy to assemble.  If we decide down the road to replace them with more expensive ones... they'll work well in the garage for storage so the have great potential long term.

Pros: Great value, easy to assemble, attractive
