Where are my books?
I probably should not have deleted and re entered the app but all my books were disappeared, gone, but still available on my phone, which is too small for reading, so be careful about Updating, I think the loss began there but not at all sure-- this app not worth the trouble except for hard to find digital books, for that it could be a service, some of the scans from public domain. Google has scanned so many books, it should offer a much much better app to present this material.
