I need to cite the 1956 Brooklyn Telephone Directory on Internet Archive. https://archive.org/details/brooklynnewyorkc1954newy/mode/2up
There is no cover or title page and no where in the directories is the name mentioned. The title from year to year changes slightly. Since I don't know the exact title is this a case where I would make something up like Brooklyn Telephone Directory, 1956 and put it in quotation marks? or since its published does it still need to be in italics?
