I was asked to take part in a short Continuous Delivery eBook from Zend. It is a free ebook, but you do have to provide details in order to download it (standard practice these days, it seems). You can also read snippets from each author in the Continuous Delivery Quotes slideshare presentation:
I enjoyed the process of contributing and reading the other contributions from some very well respected technologists.

In full disclosure: I should mention that whilst I was not provided any payments or compensation for my contribution, I can’t vouch for the other contributors, who might have required a little more persuasion than myself!
