eBooks on Android.

Hey Guys, on my iphone and ipad i enjoy how it lays everything out in i-books. For example i have a thumbnail image of all my pdf's so i know what book it is. Is there an option to have android display my pdf/eBooks with these thumbnails? It's getting kind of messy. I have a load of books and some of them don't have actual file names they are just numbers. Going in and manually changing the names would take forever. Any thoughts?
