Please, note that I provided my own definition for the terms and acknowledge that it does not match any in-universe naming convention. Also please note and compare desciptions of petty necromancers throwing what I, personally, termed as academic necromancy with what Van Hal described in Liber Mortis (and what I termed academic necromancy).I don't think this distinction you're trying to make is an actual thing
Unfortunately, I will be unable to provide full quote-comparisons until approxiamtely tomorrow.
When I was talking about different sources I largely meant variously damaged copies of Liber Mortis and sets of notes from various necromancers, which seem to be the primary vector for spread of necromantic knowledge.I think that was a later endeavour when he was doing things like raising vast armies of the undead. Even raising the dead at all seems to have required him to learn the secrets of Dhar from the dark elves.
According to Night's Dark Masters and Liber Mortis, all necromancy spells, both from the Lore of Nagash and the Lore of Vampires/Necromancers, are derivations of the spells Nagash invented. Even the new spells invented by other people are either related to or derived from his.
They aren't from different ultimate sources, they're just different lines of descent from the same source.
