The truth is out there... or maybe it's here, in this bibliography published by NASA in 1965. This "selection of annotated references to journal articles and books" spans the years 1900 to 1964. While more information has been revealed in the years since its publication, this is still an important reference tool as it includes materials not readily available today and is a glimpse at scientific research into the topic at mid-century. A good introduction for those seeking answers to whether extraterrestrial life exists in space or even here on earth too.
