Review of CMCS in the Times Literary Supplement
'The regularity and, for Celtic Studies journals, frequency of its publication, along with the high standards set by its editor, Patrick Sims-Williams, have ensured its success. Articles range across every discipline and through all the medieval Celtic languages, but the editor insists quite rightly that each piece be written so that any medievalist might understand it. For instances, all quotations from medieval languages (or from Greek or Latin) are translated. While the historical linguistic pieces cannot be evaluated by everyone, their lines of reasoning can be followed by most intelligent readers. In general, the various articles display a high degree of readability not always found in specialist journals.'
