I've been getting a lot of academic papers from Academia.edu on the subject of UFO's. It's an exceptional resource site that has increased its volume of academic papers on paranormal topics substantially, specifically in the area of UFO studies. There's a lot of historical publications that are available there and this very recent article is probably the most contemporary and thorough I've come across regarding the history of UFO research methodologies. It clocks in around 90 pages, not including the hefty appendix and reference sections of the text. There are some interesting historical cases presented along the way and even includes a nod to Christopher O'Brien's sky observation system he helped develop.
