Computational Linguistics Book Review Editor's report Graeme Hirst July 2006 BOOK REVIEWS PUBLISHED In 2005, we published far fewer book reviews than normal in Computational Linguistics: only four reviews (and another four brief notices). The reason for the decline in the number of reviewable books is unclear, but it seems to have been temporary: In 2006 we will publish about 16 reviews, so the average over two years will be about normal. 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. PRODUCTION MATTERS I am indebted to Nadia Talent for long hours of reading out loud with me to check the galleys.
