I am frequently asked where to get ebooks. I’ve put together a quick and handy reference for those of you hungry for knowledge and entertainment in the form of ebooks. Some are public domain, some are given away freely by the publishers/owners. Always read disclaimers and legal information before downloading.

EBook Management
Once you’ve amassed a collection of thousands of ebooks, you need a program to manage them. I personally use Calibre. It is in my opinion the best way to manage, organize, and convert your ebooks. Go to http://calibre-ebook.com/ to get it.
If you are a Windows user, you can also get a portable version of the application (for USB stick use maybe) here: http://calibre-ebook.com/download_portable

Dear Stenklyft,
I just stumbled across this and, Not long ago, I was collaborating on yet another eBook project, this time with someone far away – half way around the world in fact. This creates both challenges and opportunities and I’d like to explain. Additionally, I’d like to discuss how two online article authors can take existing content to fill in the gaps, combine it, and create one great eBook which they can both use to promote their businesses without competing with each other, plus, perhaps, even modify the title and sell a secondary version.
BTW great blogpost
