Making of a friendship

“Berthoud and her longtime friend and fellow bibliotherapist Susan Elderkin mostly practice “affective” bibliotherapy, advocating the restorative power of reading fiction. The two met at Cambridge University as undergraduates, more than twenty years ago, and bonded immediately over the shared contents of their bookshelves, in particular Italo Calvino’s novel “If on a Winter’s Night a Traveller,” which is itself about the nature of reading. As their friendship developed, they began prescribing novels to cure each other’s ailments, such as a broken heart or career uncertainty. “When Suse was having a crisis about her profession—she wanted to be a writer, but was wondering if she could cope with the inevitable rejection—I gave her Don Marquis’s ‘Archy and Mehitabel’ poems,” Berthoud told me. “If Archy the cockroach could be so dedicated to his art as to jump on the typewriter keys in order to write his free-verse poems every night in the New York offices of the Evening Sun, then surely she should be prepared to suffer for her art, too.” Years later, Elderkin gave Berthoud,who wanted to figure out how to balance being a painter and a mother, Patrick Gale’s novel “Notes from an Exhibition,” about a successful but troubled female artist.”
