As I was trying to keep track of characters, I was happy to see someone named Brooks, who writes a blog for his book club, took the time to document the characters of "2666" for its members. It's also good to know that there are other people in book clubs that are also blogging about their books with the same nerdy diligence as members of our PBR Book Club.
Although his blog post is a work in progress, I am impressed with his organization, tenacity, and attention to detail, such as documenting historical people including poets and artists mentioned in Book one. He created a timeline for the first book, and has created a list of victims for the fourth book.

I think I might just contact Brooks and let him know what a good job he did.
