This dictionary is a set text for my 3rd-level OU Latin course, but in my opinion it is not up to the normal OUP standard. Although edited by James Morwood, it seems to be the insensitive abridgement of a much larger work. Although the basic vocabulary is probably adequate, there are not enough phrases/idioms present, esp. on the English-Latin side. On the plus side, the print format is very clear, and the grammar section is quite good.
May suit some, but if you're really serious about the finer details, look elsewhere.
