What hharan said.
Oh, and the dictionary is absolutely horrid. There are only 40,000 entries since it's using the Miriam Webster "Pocket" Dictionary eBook. Yes, a pocket eBook, don't ask me why. Also, it cannot find words unless it is the EXACT spelling. If there are prefixes (de-, un-, pre-, etc...) or suffixes (-ing, -ed, -s, etc...) you won't find it. It's pretty much useless. Go to BN.com and look up Miriam Webster Pocket Dictionary eBook and read the reviews. Most of them are complaints about the horrid dictionary lookup on the nook.
