Following in from Station X's idea in this thread

Who has which versions of this valuable resource?
Eventually I'll pop all the data into a spreadsheet if there's enough to merit it.
I'll start off
I have a red 5 volume set and then separate volumes up to 1974/75.
The publishers are as follows;
Five volume set and year books 1957/58 to 1963/64 are Newnes.
(My 1964/65 has gone missing but I think that was Newnes as well)
1965/66 to 1968/69 Pergamon Press
1969/70 ILSC (International Learning Systems Corporation Ltd)
1970/71 to 1974/75 (the last one I have) Macdonald Publishing.
Over to the rest of you.
