OSPF DR/BDR Election explained

I read in this forum post the name Doyle mentioned in regards to a question answered by Andrew who had posted information that looked like it may have referenced a book series by Doylel so I thought if experts might be using this as a reference book it might be worth looking into. I did some digging and found the two volume set on amazon. After reading some of the references on amazon people compared this as the holy bible of networking reference book (albeit a very granular and specific area, meaning specific to routing protocols not a guide to cover all material or passing a specific test) Is it true this is a set that most network engineers should have in their arsenal? Now my eye sight is not the best so I prefer kindle on my large monitors (getting older its large monitors and reading glass on smaller devices lolo)

Anyway I am really thinking about purchasing these two books not really just for study (I am not even studying for CCIE yet) but for reference book on routing protocols for if I happen to want to see something very granular any thoughts or input on these the books or material?

Routing TCP/IP, Volume 1 (CCIE Professional Development) 2nd Edition, Kindle Edition
