I was trying to find some information on eBooks for the PSP. I have some eBooks in a few different formats, but they don't appear to be compatible with the PSP. Maybe I just need to find the right app to correct that.
I did download part of an eBook, which was really just a set of HTML pages. That worked fine, but seems to be a rather limited option since most eBooks that I have are in PDF format. I have some that are .MOBI format, and I can't remember the 3rd format that I have. Right now I don't have any other similar portable device, so the eBooks are restricted to my computer until I find out something more.
Oh... by the way, while searching, I came across audiobooksforfree.com, which isn't quite what I was looking for, but might be of interest to anyone traveling. The audio books on that site are in MP3 format.
