I read recently in the TLS that "Thomas Hardy acquired the notebook habit in his twenties, and kept it going all his long life. As well as noting down memories and events, he read widely and took copious notes on his reading, Victorian industriousness further sharpened by the hunger of autodidacticism, building storehouses of nourishment for his novels and poetry. These he referred to as his "notebooks", "pocket-books", "memoranda" and "diaries". Nobody knows how many had accumulated by the time he died aged eighty-seven, as his instructions to burn them were obeyed. Twelve of them survived the executor's flames, however, and their titles give some idea of their range: the "Architectural Notebook", the "Trumpet-Major Notebook", the "Schools of Painting" notebook, the "Studies, Specimens, etc" notebook, the "1867" notebook, and the volumes of "Literary Notes" and "Memoranda".
I wonder if such a copious note-taker would have been a blogger. Probably not. The notes were for his own use, the public didn't get to see them until they had been reworked, interwoven, sublimated into novels.
