If you already love this book - with its lush style, gothic suspense, striking characters, and passionate romance - but are still looking for the right edition to purchase, search no more. You've found it.
In addition to nicely laid-out typeface and margins, this edition has truly helpful footnotes. They point out the origin of obscure quotations, the meanings of archaic words, and the translations of the smattering of French interspersed throughout the book. Footnotes are found at the bottom of the page within the text, taking away the need for unnecessary flipping to the back of the book. And unlike other footnotes I've read, they don't waste your time pointing out things that are fairly obvious.
At the end of the book is a section entitled "Contexts." This contains helpful biographical information about the author, not just in a summary format, but in actual source documents. We can read letters Charlotte Bronte wrote while at boarding school. Or parts of her journal while she was working as a governess. Or letters to her publisher. Or responses to her book written at the time of its publication.
A section of "Criticism" follows, containing six essays, which focus on everything from assessment of Jane and Mr. Rochester's interactions to a survey of film adaptations of the book. The essays are varied in their perspective and quite interesting to read. This edition was last released in 2001, so the survey of film adaptations doesn't cover the most recent versions, but is a fascinating look at the variation within the previous versions.
My only complaint about this edition is the cover. It is burnt orange in color, and the illustration isn't one I would have picked. But the quality of the edition certainly outweighs any aesthetic concerns with the cover.
