Thanks to the blog of researcher Vicente-Juan Ballester Olmos we can find some extremely interesting data. I’ve always stated that good UFO data is a rare find online and this is one of those sources. Since year 2000, FOTOCAT is an in-progress project owned and managed by Vicente-Juan Ballester Olmos, with the purpose of creating a catalog of world-wide UFO photo events.
Amongst the many areas covered, Fotocat contains a piece of work by Italian UFOlogist Paolo Toselli. This is a database of all of the known university dissertations and theses that look at a particular aspect of the UFO subject. These official works were completed from 1950 until 2010. It can be found here.
