                      second list of Project Blue Book UFO files span the years 
                      1945 to 1949 even though Project Blue Book didn't come into 
                      existence until 1952. The files from Project Sign, Project 
                      Twinkle and Project Grudge were passed down as the project 
                      changed names or evolved into another project. Credit goes 
                      out to Emily Best for archiving these files at the Internet 
                      Archive as the primary repository. Monthly 
                      reports, staff meetings and other Blue Book briefings are 
                      highlighted in Turquoise 
                      and make for interesting reading. The 
                      Canadian UFO case files are highlighted in Brown. The 
                      classic and historical UFO cases which most UFO Researchers 
                      are familiar with are highlighted in Green. |
