Here's one of the entries on the Free Kindle eBooks list this morning.
I realize that you need a Kindle acct, Amazon acct, etc. but this will give you an idea of what's out there   huh
Damn!, beer is big business   ohmy
http://www.amazon.com/dp/B00EZV3HX2

This page is for free Kindle books, which Amazon downloads to your Kindle acct, AT Amazon  tellme
They areNOT downloaded to your harddrive  Sad

A slight correction is in order here............ :huh:
The free Kindle books are downloaded to your Kindle account at Amazon and are loaded into your Kindle for PC when you open the reader.
BUT  :-[  by right clicking on each volume then clicking "Download" the book comes down to your Kindle content folder.
I knew I had Kindle book files in Win7 so I started playing, moving files, etc. where I discovered, (or remembered) the right click thingee. What happened in Win8  :huh: I went back to the Win8 machine and tried the right click. Bingo, it works in Win8 too  :)

I found the fastest way to download was to go to the end of the list of books in the ereader, right click, Download, and keep doing the same thing (up the list) as fast as you want. As they download they disappear from the list so you just keep up with the drill until all the books in the achive are gone and they all appear in your collections. It's easy and quite fast once you get a rhythm established.  :D

Edit:  This is a good example of what I run into.  I installed it.  Ran it.  Did a simple command.  Clicked the magnifying glass to do a search.  I got "has stopped working" dialog.  Uninstalled it.  smiley

I'd suggest you be more careful and try not to break things  :o

We don't have an unlimited supply of this junk, you know!   :D

But I have not yet been able to convert the same, huge .prc file. The ebook converters epubor and Calibre are both using too much RAM in an unpatiently way...; they freeze to death before there is enough memory available. I guess 225MB is quite a job. Do I really have to buy a new computer, in order to convert this ebook into a more useful format?

modified:
At http://ebook.online-convert.com/ I can convert the file for a mere $5. Cheaper than a new PC.

A file over 100mb  :huh:
The largest file for online conversion is usually limited to 100mb

Go for it!   :P
