I learned from Sandy Kemsley (read the original post on column2.com) that Springer is now offering many interesting books and journals for free.
So, if you watched the Fundamentals of BPM MOOC videos and want to deepen your knowledge this is a great opportunity to read the Fundamentals of Business Process Management (2nd edition)!
Fundamentals of BPM (and many other interesting books) available for free on Springer
