The listing is for the three volumes of the ESRI ESRI Guide to GIS Analysis set.

Volume 1: Geographic Patterns & Relationships  186 pages

Volume 2: Spatial Measurements & Statistics  238 pages

Volume 3: Modeling Suitability, Movement, and Interaction  419 pages

Lavishly illustrated with color maps, diagrams and charts.  Although published by ESRI Press, the topics, examples and analyses do not mention or require particular ESRI software; these books are applicable to anyone interested in GIS analysis equipped with GIS software that contain the requisite spatial analysis tools.  

Vol 1 and 2 are in very good unmarked condition.  Vol 3 is also unmarked but shows use on its smudged cover and rounded corners.
