I'm not sure this is the right Stack Exchange Community for this question, but here I go.
I bought a book on Machine Learning from a (I believe) popular publisher a few days ago. It's a first edition and it was first published on September 2015 (4 months ago). The point is, in the first 50 pages I found around 5 errata. Not huge ones, but errata nonetheless. Even though the book is quite good, finding that many errata made me a bit uneasy.
Could this be considered normal, as it is a "just born" book? Or should I be concerned in any way?
