Back in 2007, I gave a talk "'I should be loving this': Sylvia Plath's 'The Perfect Place' and The Bell Jar" at the Sylvia Plath 75th Year Symposium at Oxford in October 2007. I was lucky enough to have a second opportunity to read a slightly revised version of it the following spring at a weekend Symposium at Smith College.
Here is a Loom recording of the talk which is now on YouTube. Additionally, the talk was further revised and published later in 2008 which you can read in the the Articles and Essays section on my Resources page on A celebration, this is.
