Here is draft #8 of Visually Observed Natural Re-entries of Earth Satellites:

http://satobs.org/seesat_ref/misc/Visually_Observed_Natural_Re-entries_DRAFT_8.pdf

Three re-entries have been added that occurred on the following dates: 

1965 Apr 04
1974 Aug 01
2014 Jan 16

I have also begun the next phase of the work, which is to build a set of web pages on the subject. Included, will be
reports on cases that I found especially interesting, or for which the correlation between sighting and known re-entry
might be less than obvious, for example, due to limitations or problems with the data. Several of the oldest cases were
solvable only after systematic and other errors in the historical 2-line orbital elements were recognized. Some were
solved despite the lack of availability of official TLEs.

I have just completed the first case study, which happens to be one that I discovered only last week. I enjoyed working
on it because of the way in which it came to light. It caused a mass UFO sighting in Venezuela in the summer of 1974,
seen by thousands, with front page newspaper coverage, then was quickly forgotten. It only began to emerge from
obscurity decades later, when two Americans who witnessed it in their youth told their story:
