... is what Those In The Know have told me several times. I use this book (and those covering neighbouring counties) to guide me round historic churches. Even I have noticed inaccuracies, but the value of the series lies in providing clues which you would otherwise have missed, and leading on to other features. It is so convenient having all this information in one portable volume. I have been surprised by some omissions. For example, it beats me why the fine Church of Scotland in Occupation Road, Corby, is not mentioned. However, such criticisms seem churlish in consideration of the monumental achievement that is this series of volumes. So, yes, use the book as a valuable tool, while not necessarily believing all you read in Pevsner.
