Don't buy a bundle of books to start. Just buy one for testing. When I transfer Adobe Digital Edition books to my PRS-505 the formatting gets roughed up. It may just be the individual books I bought, I don't know for sure.
Things to look for.
- Initial font size is very, very small with huge 1.5" margins.
- With PRS-505 enlarged font size , (+), I loose right justification.
The following all occur with enlarged font size:
- Page numbers don't match between book and reader.
- It takes 2-3 page turns to make it through one book page.
- Unexpected line breaks.
- Unexpected page breaks.
- Extra (empty) lines.
If you aren't bothered by the formating, the content is still the same.
