GeoServer is one of the most importants open source geospatial servers nowadays. Implemented in Java, based on the powerful GeoTools libraries, GeoServer offers a great degree of interporability publishing data from major spatial data sources using Open Geospatial Consortium (OGC) standards.

Chapter 12: Going Further: Getting Help and Troubleshooting
Despite of its title, the book is great from newbies to those with intermediate knowledges on GeoServer, and also put some efforts on advance topics, like performance and configuration for production environment chapters.
Personally, I like the way Stefano writes: simply, plain and, most important, making clear complex questions. In addition, the book is plenty of samples and figures which help us to understand better what is talking on.
Conceptually, we can divide the book in three sections: introduction (chapter 1, 2 and 3), basic or common usage (chapters 4, 5, 6 and 7) and advanced topics (chapter 8, 9, 10 and 11).
The book introduces us in the GIS world (chapter 1) starting with an introduction of many related topics: projections, coordinate systems, modeling information, etc. After this, it shows how to install GeoServer (chapter 2) in two different operating systems: Ubuntu Linux and Windows and finally, passed to show the main aspects of the administrative interface of GeoServer (chapter 3).
From here, the book covers the main aspect on how to access, add and serve data (chapter 4 and 5), how to style to serve them in a better way (chapter 6) and basic samples on how to create maps against GeoServer using Google Maps, OpenLayers and Leaflet libraries.
The third block, concentrates improving the performance of the server using the GeoWebCache system (chapter 8), administer GeoServer via its REST interface (chapter 9), securing its access and administration (chapter 10) and tune it up ready for a production environment (chapter 11).
The book is mainly oriented to WMS but dedicates the chapter 12 to talk specifically on WFS and WCS, also supported by GeoServer.
Without a doubt, GeoServer Beginner's Guide is a book must be on your working table.
