We just managed to link the paper and electronic version of the Clustering Deep Dive. This means that if you buy the paper book today, you can get the e-book at a discount. This was something a lot of you have asked for, so we pushed it through. Unfortunately, it did mean we had to re-upload the book to a different back-end system and “history” is lost, so those who already bought the paper version of the book, unfortunately, can’t get the same deal. If you are interested in getting both versions, go here. Or click below on the book, or one of the other books I recommend reading 🙂
