Description: The log book of spectroscopic plates obtained at ESO telescopes until 1984. This log is probably incomplete. The plates themselves have been given to the observers and no copy is kept at ESO. Unfortunately, there is no possibilty to provide the current affiliation or the address of the plate owner.
