I've begun annotating part 2 of Roberto Bolaño's The Savage Detectives. You can view the work in progress here .
The second part of the novel covers 30 years, 445 pages and is made up of interviews with various characters. I started this project as I was reading the book because I was having a very difficult time keeping track of the characters. At the time of posting, the document only lists names up to where I am in the novel (p.377) and has no actual annotations, but I'll be filling in my notes as time allows.
