Most publications start with a reference to the blog post blog by Martin Fowler and James Lewis entitled Microservices, published in March 2014. In this article, the authors describe many of the features of the microservice architectural style along with the underlying philosophy.
If you are looking for a short description of the architecture style, you should take a glance at the book Fundamentals of Software Architecture by Mark Richards and Neal Ford. There the most important patterns and tradeoffs are explained in a single chapter.
For a more elaborate presentation of the topic, it is worth taking a look at the book Building Microservices by Sam Newman.
