From what you have read or heard about, which is a good book on fuzzy logic/sets/systems? I'm interested in basic of fuzzy systems, fuzzification/defuzzification, etc.
here is the best book I would recomend for the subject: http://www.amazon.com/Fuzzy-Sets-Logic-Theory-Applications/dp/0131011715
Here is an easy to read book: http://www.amazon.com/Fuzzy-Logic-Revolutionary-Computer-Technology/dp/0671875353
Besides here are a list of links that might help: http://www.seattlerobotics.org/encoder/mar98/fuz/flindex.html http://www.fuzzy-logic.com/ http://videolectures.net/acai05_berthold_fl/
If you are looking for exhaustiveness, Springer has the Handbook of Fuzzy Systems series which covers most topics. I particularly recommend Fundamentals of Fuzzy Sets edited by Dubois & Prade which was particularly helpful to me when I was taking a graduate class in uncertainty modelling & possibility theory (with one of the editors/authors).
