"EDA", "PDA", and "NSA" are fan-created titles for stories which were all released under the exact same branding. (Eg Mad Dogs and Englishmen being advertised as the 100th.) The separation of "series" into titles obscures connections like the Eighth Doctor component of Fear Itself or the "Past Doctor" component of Interference.) Distinction between Eighth Doctor and previous Doctor novels can be better achieved by prose fiction overviews for Eighth Doctor novels etc analogous to Eighth Doctor comic stories.
