Archaeology Related Texts:
Digital Archaeology by Thomas L Evans and Patrick Daly
Actually, this is a new book that I haven’t had chance to read yet, but Tom used to be the Head of Geomatics at Oxford Archaeology and did a lot to move the department forward so I’m sure it will be good.
Spatial Technology and Archaeology by David Wheatley and Mark Gillings
This is one of those texts that anyone who is serious about doing good quality geospatial analysis with archaeological data should read.
Landscape Archaeology and GIS by Henry Chapman
Another good read on applying geospatial analysis and archaeology, with an emphasis on landscapes rather than specific sites
General GIS:
Open Source GIS: A GRASS GIS Approach by Markus Neteler and Helena Mitasova
This was incredibly hard to get hold of for a while, but the third edition is now out, and it’s a must if you want to get into using the grand-daddy of GIS packages.
Web-Based GIS:
Web Mapping Illustrated by Tyler Mitchell
For an outline of the whole area of web-based mapping, this is hard to beat. Amongst other things, it gives you the clearest set of instructions for installing PostGres/PostGIS that I’ve seen, and a very useful glossary of MapServer commands.
