First complete reading and annotation. Wow! A very important volume with no equivalent hitherto produced as far as I know. Essential reading for anyone interested in not only the history of chanty publishing, but the history of the chanty itself. I have most of the collections mentioned in it but of those I don't have I can now prioritise which ones are worth acquiring. Another important feature is how many of the publications are at least partly derived from earlier ones. It's also helpful to know how different editions differed. The book is also a useful summary of the very long 'Advent' thread here.

I hope Gibb is at least thinking about the next volume.
