Thespian*: I'm more concerned with e-book DRM policies. ;)
SeduceMePlz: My friend declined the optional DRM offered by Amazon to authors publishing for Kindle, so the book should have only whatever DRM if any the Kindle format itself contains. (I'm not very familiar with Kindle... ?) Also, he opted for non-exclusive publication (at the cost of receiving a much lesser share of each sale) and can publish the book elsewhere, so I can forward suggestions to him if you have a preferred provider?
IIRC (I recall reading about it when I begun to use "Calibre" -for those of you who still don't know it, that free software is like the iTunes for e-books-), the Kindle DRM is linked to the device by way of its internal identification number (like IMEI in cell phones). If your friend declined to use it, maybe the book have no DRM. :)
In that case, I'd feel grateful to receive one of the codes, if I may. :)

Because of my current condition (long-term unemployment) I'm restricted to public libraries and friends (for physical copies) and e-books offered for free by their authors, like the ones published by Baen Books in their [url=http://www.baenebooks.com/c-1-free-library.aspx?__utma=222178315.965305642.1379493905.1379493905.1379493905.1&__utmb=222178315.1.10.1379493905&__utmc=222178315&__utmx=-&__utmz=222178315.1379493905.1.1.utmcsr=google|utmccn=%28organic%29|utmcmd=organic|utmctr=%28not%20provided%29&__utmv=-&__utmk=113501700]Free Library[/url]. ;)
(They have a fair amount of authors offering copies of some of their books for free. However, they stick to sci-fi and fantasy settings.)
Perhaps someone else may provide the name of some publisher not including any kind of DRM in its releases unless specified by the author?
