I have two copies of Tolkien's "A Middle English Vocabulary". Both are dated 1922 (ie M DCCCC XXII) on the front cover and the title page. There are some differences, though -

Copy (A) says "Printed in England" at the foot of the title page; copy (B) does not.

In copy (A), the advertisements at the back are headed "Middle English"; in (B), they are headed "Early and Middle English", and dated "October 1921".

How do I tell which is the earlier? I find the comments in Hammond & Anderson a little confusing.

Thanks
