So this was lovely. It is a series of essays about a volume of poetry once belonging to Maria Branwell Brontë, and descriptions and analyses of the fragments of juvenalia and marginalia found within. It has lots of detailed photographs and explanations of the literary, political and social environment in which the Brontës were writing.
All of the essays emphasise its importance and its influence on the Brontë children, particularly Charlotte and Emily, and all have a similar theme:
"former owners can embed themselves within its pages, and therefore an enduring bond to the book itself as a physical object" (p 69).
As an underliner and margin-scribbler myself, I found this very touching.
Just an aside, the story of the book's provenance and how thrilling it was for the Brontë Society to finally obtain it (in exchange for a six-figure sum) just reinforced what I've always thought - that artefacts of literature belong in the public domain, where they can be used to contribute to humanity's body of knowledge for the benefit of everyone. People who profit financially from dealing in artefacts are despicable.
