Other still older ones (to 1972), by year, are now available here (as ZIP files).

These are in simplified text with only the date, time, call, freq, state, and city (i.e., no format/program notes or mileages).   They also do not show any re-logs during the same CST calendar date (even if 12 or more hours apart) so some caution is advised if using them to generate any detailed E_s drift-plot maps.

And yet even older, 1962-1970 & 1971.
