I completed the Aurelia Plath shorthand project in February; it had taken another trip to Bloomington's Lilly Library, last September, to double-check all the correspondence in the Plath mss. II Boxes 1 through 6a.
On April 15, Mrs. Plath's estate granted me permission to use the findings for scholarship. Now I feel completely free to write. November's Sylvia Plath Conference in Belfast will coincide with the publication of The Complete Letters of Sylvia Plath and I will be presenting a paper there about Mrs. Plath's shorthand annotations, which I call "metadata," on said correspondence.
