1970 ff logbooks

this is my first logbook from 1970. Just a few pages shown. I used logbooks mainly 1970-95. Most of the information is now in iNat, with the exception of dubious identifications without a corresponding specimen in the collection.

in later years, the logbook became more organised and later it was based on single sheets

in 1978/79 I was programming at ETH Zurich and had access to its mainframe computer. I entered all observations on punch cards (IBM) and had the sorted output printed on a chain printer. It's a massive pile, I still have a copy of the 256 pages output. Lost the 12,800 punchcards (7 boxes).
