My review of the new translation and edition of Johannes de Grocheio‘s music treatise has been published in the journal Speculum.
The link a the bottom of the page is the official one to the CUP site, which requires institutional (or personal) subscription. According to the permissions information on the CUP site, however, I can also post a more freely available pdf here too (directly below).
