Most of the pages have been hole punched and pages separated and stored in a ring binder, but these are still useful for reference.
Some of the catalogues appear to be complete - these are 25th edition (1984), 28th edition (1987), 27th edition, (1986) 19th edition (1978), 20th edition (1979), 24th edition (1983) - I think these are the right years, but please check if you are not sure.
