I run an electronic mailing list devoted to discussion of the life and works of William T. Vollmann. To join the list, send an e-mail to firstname.lastname@example.org with the following in the body of the message: "subscribe wtv-l [your-email-address]".
Once it has been confirmed that you have been added to the list, you may send e-mails to the list members at email@example.com.
I shall add more information here on Vollmann and the list as time allows. Access those materials via the links to the left of this text. You will find some useful information regarding use of the list at http://www.bu.edu/tech/comm/email/majordomo-mailing-lists/.
