I think this is also the first photographic shelfie, a 21st century term for a curated intellectual self-portrait using books or other objects on bookshelves.
Note the co-existence of many binding structures: extra boards bindings (left, top shelf), boards bindings (bottom, middle, spine torn near head and creases along spine) cloth case bindings with a natural hollow and paper labels (inferring from the smooth, uncreased spine), wrappered periodicals(?) with printed titles; and a large number of traditional leather bound books.
This is around the time period we will be examining in detail in my upcoming Early Nineteenth Century Bookbinding workshop. It’s exciting to have contemporary photographic evidence to add to the context of these books. If 19th c. photographs and books interests you, Carol Armstrong’s Scenes in a Library: Reading the Photograph in the Book, 1843 – 1875. Cambridge and London: MIT Press, 1998 is also recommended.
