You are correct, of course; the files are 20 mb and 57 mb. I did further tests - first I opened them with my computer (they were ok), then tried other google books files, and finally I extracted 10 pages from a pdf file and tried that small file but with the same result as with the entire file. Next I used a different app for the reading - the A500 came with 'LumiRead' - I downloaded and tried an app from the Android app store, 'ezPDF Reader'. The new reader worked ok, sort of. It produced very clear, beautiful pdf text, but the problem was that it needed to load separately each page and the loading took about 30 seconds to a minute to complete. I think it slowness is related to the 600 dpi resolution and size of each pdf image page of Google Books scans.

I'm not sure if I want to pursue this problem further; I could try reader after reader, perhaps one of them will work properly with the large Google Book images - the pdf readers are generally fairly costly, but perhaps the problem might be caused by the A500 firmware or insufficient memory.

It seems to me that the manufacturer should have insured that their 'LumiRead' worked properly.
