The bible for 19th century lithography is Color Explosion by Jay Last.
Its an absolutely brilliant work, covering each of the main lithographers and some of the minor ones. Its a weight tome filled with colour images on each page. Its not focused on cigarette cards, but it does cover them enough for VNSF members to be satisfied (my view).
Its quite pricey on Amazon, but it sometimes parts for c.$30 - $40 if you keep watching.
Each litho company went through multiple transitions as partnerships dissolved, formed, parents handed to children etc. Jay Last covers the main points of each lithographer. And provides a general historic commentary for the 19th century development of lithography.
For example, the Thomas H Hall brand was lithographed by Heppenheimer & Maurer for many years, until they rebranded as Heppenheimer Sons in 1886 (which gives us a clear cutover date for some of the N342 black background cards).

(ii) And any cards pre-1885, particularly Thos. H. Hall.
