My 2013 Lovecraft Annual has yet to arrive, but Wilum Pugmire has perused a copy and winkled out a nugget ‘o news, on a new S.T. Joshi volume…

The Variorum Lovecraft, to be publish’d by Hippocampus Press in four volumes. […] could begin publication as early as next year, I hope to present all the relevant textual variants for all the stories that Lovecraft wrote over his short literary career. […] may include the printing of passages from handwritten or typed manuscripts (chiefly the former) that were excised as Lovecraft was writing the story or as he performed a subsequent revision of it.”

Sounds like the ideal candidate for an interactive electronic edition?
