The book comes from Morrowind.
The sad part is, in Morrowind you got to meet its author and it made perfect sense for that man to write such a book.
A lot of Morrowind books told tales about places you could actually go to, people you could actually meet.
This made these books even more special.
Now, in Skyrim, when you read about the Gnisis cornerclub in Charwich-Koniige or about master Neloth, or about the canols of Vivec in Breathing Water, what does this mean to you?
Why is there no new lore about places and people in Skyrim? (same for Oblivion for that matter.)
Why must they feed off old success instead of expanding upon it?
The "new lore " is there,even if you've not founding yet probably
i.e. The Falmer,Dwemer,Forsworns etc. we have even "touristic guides"

to the major towns - and don't forget "uncommon taste"

i repeat,these Books are the best written part in Skyrim,apart from the old ones from Morrowind and oblivion still present of course.
Unfortunately i don't remember all the titles now,but some of them are really well written -for a game standards of course.
And don't forget that there are more "new players" than older,so even the old books came to new life to them.
And even to the old players sometimes; how many of them at the time of Morrowind and Oblivion had read all the books after all ?
