The CD edition was prepared by Sheridan Williams and myself, and it covers the first 100 years of the Memoirs, which is one reason why the last few volumes were not included. Another reason is that we still have a large number of printed copies of the last few volumes for sale, so if anyone wishes to have them they can buy the paper copies. If there is another CD edition in a future year we might include the later volumes. As has been mentioned above, the Halley Memoir is available (as an exception) online, but the others are not. I am glad that the CD has sold well. For those interested in the old publications, we do have copies of many Memoirs for sale beyond those listed on the BAA website and do please ask me for details using my contact details in the Journal, if you wish.
