Building a collection of reference and academic texts on GIS can be costly. There are some free online source materials that can be a valuable contribution, especially if your book budget is nonexistent. Most of these free GIS books are available in PDF format and can be read from a computer or on an eBook reader. A few are only available online.
Free GIS books from the National Academies Press
A good starting place for finding GIS books is the The National Academies Press site which offers over 4,000 titles in PDF format for free from its site. For example, a search for the term “GIS” returns over 1,100 results.
Map projections manual
The classic book, “Map Projections: A Working Manual“, has scanned by the USGS and made available for free online in both PDF and DjVu formats. The volume was originally published in 1987 and was written by John P. Snyder. The book provides an overview of the “appearance, usage, and history is given together with both forward and inverse equations for each [map] projection.“
Urban planning and GIS
This urban planning and GIS book entitled, “GIS in Sustainable Urban Planning and Management” is an open access book focusing on the use of GIS in sustainable urban planning and management includes six chapters containing exercises and GIS data that can be accessed to learn how to reproduce some of the analyses from the book using QGIS.
The third edition of “Geospatial Analysis – A comprehensive guide” is available for reading online and “covers the full spectrum of analytical techniques that are provided within modern Geographic Information Systems (GIS) and related software products”. The book was written by Michael de Smith and Paul Longley of University College London, and Michael Goodchild from UC Santa Barbara. PDF versions of the book are available for purchase from the site.
Free Open Access Book: Google Earth Engine Applications
This book features research on using Google Earth Engine to access and analyze GIS Data. The over 420-page book contains 23 articles reprinted from a special Google Earth Engines Applications issue originally published with the journal Remote Sensing.
Published by MDPI Books and edited by Lalit Kumar and Onisimo Mutanga, the open access book features a range of case studies using Google Earth for processing GIS data.
Some of the case studies include: mapping mining areas in the Brazilian Amazon, monitoring the impact of land cover change on surface urban heat island, estimating satellite-derived bathymetry, and drought assessment using global soil moisture data.
The book is available for free as an open access book in PDF format under a CC BY-NC-ND license. Those who want a printed version can purchase a soft cover format from the same site.

Beyond Mapping Articles
This resource isn’t technically a free GIS book resource but:
Spanning from 1989 to the present, the collective articles from Joseph K. Berry’s Beyond Mapping column in GeoWorld Magazine are available on the InnovationGIS.com web site. Berry has written extensive about the subject of GIS over the past 13 years. His articles cover topics including spatial analysis, the direction of GIS, geospatial technology, and applications of GIS techniques.
The articles are listed chronologically but are also in the process of being assembled by topic. Currently, Beyond Mapping III, which compiles articles by topic from 1996 to 2007 is available online as well. Beyond Mapping I and II are currently being prepared. Most articles older than July of 1996 are not entirely online yet. There are a host of other materials covering GIS exercises and course materials which can be accessed by visiting the InnovationGIS home page.
