Just a thought to put into this. In the world of scientific publication, learned journals etc. it is now common practice to make these available on line after a certain length of time. It varies a little from journal to journal but a period of about a year would be typical. This encourages people who want to be up to date with cutting edge developments to pay for their journals (or more typically the institution for which they work to pay) after which the rest of we peniless rabble can have access to the data. It seems to me that Graham is already doing more work than most, so would not want to burden him with any more, but if there is a real move to make old MPHs available then perhaps something on these lines might be acceptable. A Merry Xmas to all readers.
