Construction Specifications Writing: Principles and Procedures

Aside from CSI's Construction Specifications Practice Guide, this is the best book in print on specifications writing, by some of the most experienced experts in the U.S. As an introduction to specifying it is very good and is a good companion to the PRM. It includes samples of all the types of information commonly found in specifications, from AIA standard forms to short form specs, some of which are not included in the PRM.
