I’m a bit late to the party on this, but better late than never, especially when it’s this good!
I’ve known that Project Gutenberg has provided tons of free e-books for a long time, but I’ve always been a bit too lazy to use it regularly. It’s so easy to just order something from Amazon rather than have to download from Project Gutenberg to my PC, hunt down my Kindle’s USB cord, plug it in, download the file, then disconnect. (Yes, truly lazy…)
Well, no more excuses: The Magic Catalog is an indexed list of many thousands of books available on Project Gutenberg that lets you immediately bring down any listed book to your Kindle just by clicking on it. So, once you’ve down this one more manual download of the Magic Catalog itself to your Kindle, you then have super-easy access to all those books going forward.
Go to this link here, download the MOBI version to your PC, and then transfer that to the documents folder on your Kindle. It’ll take a while to index, but after that you can search and download directly to your heart’s content.
