I have found no less thanfour diaries for 1973, all of them incomplete:
My “real diary”, the one I kept from 1963, in this
case volume 9, started on 10 June 1970 and kept continuously only
until 1 October 1970. There are about 30 entries for 1973, spread
between April and October.
A pocket “business man's diary” from Collins, in English and one opening per week. I
appear not to have used this much for making notes
A pocket diary published by BASF in
German, also one opening per week. There are some relevant entries here.
A UNIVAC diary that I presumably got
when I joined the company, in German and one opening for 2 months. The notes are mainly
work-related.
