Simon & Schuster vp, business information and data operations Helene Green died Tuesday after a long illness. She began her publishing career at Macmillan in 1987 and joined S&S's children's division, responsible for inventory, in 1994 upon the acquisition of the company (which owned Scribner), after which she moved over to the supply chain division. Green also represented S&S on various AAP and BISG committees. VP, business operations Frank Nunez said: "Helene will be remembered as a consummate colleague: knowledgeable, passionate about the work we do and eager to do a good job, loyal to her staff and a great teacher to many at Simon & Schuster. Most of all we will remember her as a friend who we will miss." In lieu of flowers, donations can be made to Memorial Sloan Kettering Cancer Center in support of ovarian cancer research. A funeral service will be held on Thursday, June 12 at 11:15 am at Riverside Memorial Chapel in New York.

George R.R. Martin did set up a Twitter account -- as @GRRMspeaking -- but his first post warns, "I don't tweet all that much, please check out my live journal page." In the comments on that blog, he confirms, "it's legit... though I don't plan to go on Twitter myself. It is a defensive measure against the various fake Twitter accounts that have sprung up. Essentially my minions will be using it to echo news and comments from my Not A Blog."
