This truly is a handbook for researchers, in being a very short and thorough reference. However, I wouldn't recommend it for someone just learning network theory on their own. The author is often more interested in giving formalized definitions, terms, and examples than ensuring the reader understands the basic concepts of SNA. It reads like a legal or engineering document, more than an introductory guide. That's probably good for economy or business students, but not to an anthropologist like me. The other two books that are recommended by Amazon to buy along with this one both offer the same information, but they also do it in a way that is more readable if you want to actually do SNA. The concepts of SNA are very simple, yet the author does his best to make them sound more complex or esoteric than they are. The book is just fine, but the 3-stars is a comparison of the other into works out there, and my experience reading dozens of articles on the subject.
