I return to this book again and again when researching Insular manuscripts. The first part of the book discusses each known Insular ms, what is known about it, where it was made, the name of the scribe where known, etc. It also lists publications that have discussed this ms, particularly scholarly. The last section consists of black & white (mostly) photos of pages from these manuscripts. The photos are mostly small, but there are examples from each of the manuscripts listed earlier. The book seeks to be a comprehensive list, and appears to truly be so. ( )
