The title of this book might be slightly misleading, as it suggests the book covers topics both in linguistics and logic. This isn't so, as the introduction to the book explains. The title is a collection of introductory articles (~80 pages each) for a number of topics which are located on the linguistic/logical interface. Therefore, you will find here a selection of important topics from that area: an introduction to categorial type logics, Montague grammar, type theory as applied in linguistics, situation theory, game-theoretical semantics for languages and so on.
The book is a quite exhaustive compendium - no doubt, it is written from a specific viewpoint, so don't expect any articles on contextualism, but it does a really good job of sketching the field as it looked like 12 years ago. This doesn't mean the material is no longer current - on the contrary, most of the mentioned approaches are actively being developed and the Handbook still provides a worthwhile introduction.
A real advantage of this handbook is the choice of authors. Many of the authors are either the creators or very active developers of theories they write about, so their take on the described area is as representative as it can get. The editors did a really good job of putting together a team of authors that created over 1000 pages of quality material. While the Handbook carries a hefty price tag, the material is most certainly worth it. For any person working actively in the field or even for the more specialized graduate students, this is certainly a must-have.
