Amendments and additions – most recent first

On the first page of this site I wrote that there are likely to be continual changes as these notes are added to and the pages develop over time. Looking at other sites I’ve found I have a problem discovering what has changed since my last visit so, in an attempt to track what I’ve changed myself, I’ll make a determined attempt to keep this up to date by using this page to record each change.

However, although each reference will take you to the actual comment, when there is more than one change on a single page you will be taken only to that page and will then have to look down for the amendment or addition.

The latest additions and amendments to any of the pages will be marked by a pale background – as in this paragraph. I hope this will be sufficient to mark changes and be relatively easily seen.
