Introduction to Machine Learning by Alex Smola and S.V.N. Vishwanathan. (PDF file)
From the preface:
Since this is a textbook we biased our selection of references towards easily accessible work rather than the original references. While this may not be in the interest of the inventors of these concepts, it greatly simplifi es access to those topics. Hence we encourage the reader to follow the references in the cited works should they be interested in finding out who may claim intellectual ownership of certain key ideas.
If you need a machine learning textbook with accessible references this is one to consider.
I first saw this in a tweet by Peter Skomoroch.
