The current issue of Bookforum has a delightful profile on what it takes to be the literary executor of someone like Auden (via Light Reading):
Eventually, Auden asked Mendelson to take his place as the editor of the collection [of essays] and sealed the deal with a $150 check for photocopying expenses. Mendelson was so happy that, as he tells it, he jumped up and down. As their collaboration progressed, the poet was also pleased. According to Mendelson, who took the liberty of vetoing an essay that he thought wasn't very good, Auden was grateful for the critical judgment—plus, "he was delighted to have somebody actually pay attention to proofreading." When the project neared conclusion, Auden asked Mendelson in the postscript to one of his letters to be his literary executor. Mendelson agreed. In the end, the photocopying only cost $110, so he sent the poet $40 back.
To honor the centenary year of Auden's birth, a number of events have been scheduled to celebrate the poet's life and work, including readings and tributes, a BBC4 television special, and martinis served at his birthplace, on his birthday, February 21.
