You know, I never actually realised you could search for books in your library. I've been paging through mine or using shelves to organise it. Because I thought that's what you did.
Using the series information properly, I can see how I don't have to rely on shelves - I can search!
For anyone else silly enough to have not known this, press the icon near the battery, the three little lines. It says SEARCH there. I really wish they gave you a proper manual with these things.
