Diesel eBooks, my preferred non-DRM eBook store, is shutting its doors end of march 2014:
Diesel eBooks is Closing
Diesel eBooks will be closing at the end of this month. It's been a great ride! We're exploring our options - eBooks are still in the infant years and there are many opportunities opening up now and in the future. We want to thank you for being such loyal customers. Understand this doesn't necessarily mean you won't see Diesel in another form in the near future.
IMPORTANT: you must download your eBooks here by month end. Downloads will not be possible on April 1st.
The Team at Diesel eBooks
I liked to buy eBooks from them because they provided DRM-free eBooks in the standard ePub format.
Now I've got to find a new one, preferably from the Guide to DRM-Free Living: Literature list.
