From Introduction: "This part of Bulletin contains 250 European patents that relate to retorting (and distilling underground), refining, and utilization of oil shale and its products. The largest single group, of which the majority was assigned to a single company, relates to fluidized handling shale. The patents are arranged numerically, and alphabetical list of investors and assignees follow them. A classified list of all the patents follows the author index of Part III. Parts I and II were published in 1958."
