Computational Linguistics Book Review Editor's report Graeme Hirst May 2007 BOOK REVIEWS PUBLISHED In 2006 we published 16 book reviews in the journal, plus a few brief notices. Most reviews are published in a timely manner -- that is, within 12 months of receipt of the book. This allows six months for the reviewer (most take less) and five months for journal production. MATERIAL REVIEWED I am continuing to be fairly strict in deciding if a book is to be reviewed, but try to include all books that are in "core" computational linguistics, as well as a variety of books from adjacent and overlapping disciplines that are likely to be useful in CL. We do not review technical reports, doctoral theses, conference proceedings, or workshop proceedings, except if revised for publication as a book by a recognized publisher. Sometimes it has proved to be impossible to find a reviewer for a book who has sufficient expertise in the subfield and yet does not have a conflict of interest due to an association with one of the authors, editors, or contributors of the book. PRODUCTION MATTERS I am indebted to Nadia Talent for long hours of reading out loud with me to check the galleys.
