HI Charles - and welcome to the forums.
Does anyone know how to delete a book that shows in the library?
You can't delete a book from within the Android app. If you are using Logos 5 you can "hide" a book (details at http://wiki.logos.com/Hiding_Books) and this will be synched to your mobile devices
Alternatively you could set up tags within your library on Logos 5, set up a tag for books you want to see on your mobile device and then filter the library on that device using that tag (tagging details outlined at http://wiki.logos.com/Tagging
My librsgy is crowded with unwanted books thst havd been downloaded from vyrso.
Presumably these are books you purchased - in general, purchased resources are made available on all platforms you own assuming they are licensed for that platform.

If Book has been downloaded go into library click little i on right hand side and when new panel opens click red remove button.
If you use filter local: in the title list it will only show downloaded resources
