Cut-off date. The cut-off date of the original print Annotated Bibliography was December, 2007. But since digitization, it has been updated. Being digital it is now possible to be always current with continual updating. None the less, it is not unlikely that some items published before and up till  2007, or even after, may not have come to the attention of the compiler. We will be grateful if users can bring these or any other omissions as well as errors to our attention.
