A well written, easy to understand book and has many examples of how to implement and use cluster analysis. Recommended first book for those just starting cluster analysis.
These are okay for a quick overview of cluster analysis but are not comprehensive in their presentations. There are a number of other web sites on cluster analysis but these are the ones that have some usable information for people beginning cluster analysis. Most of the other sites are wither too brief to be usable or are links to software vendors selling clustering software.
http://www.statsoftinc.com/textbook/stcluan.html This is a good overview site with brief descriptions of various clustering methods and graphics on cluster results.
http://trochim.human.cornell.edu/tutorial/flynn/cluster.htm Very brief presentation of cluster analysis but has links to other related statistical methods such as factor analysis, multidimensional scaling, etc.
http://www.pfc.cfs.nrcan.gc.ca/profiles/wulder/mvstats/cluster%5Fe.html Another very brief presentation but does have a few good comments on selection of number of clusters.
