Hi, EE... I'm looking at a run of city directories from Reno, Nevada. The full title of these (and other) directories runs just under 100 words (see the attachment). I'm leaning toward just using this as the title (assuming all years have the same title and I adjust for the years that I cite):
Polk's Reno City, Washoe County and Carson City Directory [run of years]
Is it necessary to use the entire 100-word title, or am I OK using what I have above? Thanks for your guidance.
