First review with words, huh? Hmm, that's a bit of pressure...
So, I've decided to read a chapter of the New Cambridge Medieval History a day until I get through the whole eight books, because apparently eight years late is the perfect time to work on your mediaeval history college work. The first volume in the series is a solid and mostly comprehensive work on the transition between the late antique and the early mediaeval periods.
In general, the articles (each written by experts in the particular field) are clear and informative, although I think a stricter editorial hand would have been useful, in particular in the articles by Barbero and Loring on Visigothic Spain (which have some weird turns of phrase and non-standard constructions) and some of the thematic chapters in Part III (which can be somewhat disconnected). The common problem of untranslated phrases in the body of the text is also apparent in quite a few articles. (Seriously, nothing grinds my goat more than people throwing in untranslated phrases to show off.)
So, those issues knock off a star. Other than that, though, it's definitely an interesting read. Understanding the development of the Middle Ages is impossible without seeing its roots in earlier society. A must-read for any serious student of mediaeval history.
