Most of the Negative Search Report Forms were destroyed about 1978. There was a massive amount of them, and taking considerable storage space. I felt the scientific value had long since past: the last ones from the late 1960s. They were of value only if something was discovered later, and we could look back and verify "not visible then."
Some completed negative search report forms from 1967 and 1968 were never properly filed with the earlier reports, and were not thrown out in the cleanup done about 1978. Some  are reproduced here. I have copied all of the available reports made by David Levy and Hugh Maclean that were found. I have made one copy of reports for each other individual found.
