A trove of Brontë family manuscripts—virtually unseen for a century—will be auctioned by Sotheby’s as part of what the auction house is calling a legendary “lost library” of British literature treasures. The Honresfield Library includes a handwritten manuscript of Emily Brontë’s poems with pencil edits by Charlotte, letters, inscribed first editions, and the family’s heavily annotated copy of Bewick’s History of British Birds (which features in the opening scenes of Jane Eyre).
