In his column for the London Review of Review of Books, Keith Thomas has written a fascinating history of scholarly note-taking, with a great deal of nostalgia for the dying art:
When I go to libraries or archives, I make notes in a continuous form on sheets of paper, entering the page number and abbreviated title of the source opposite each excerpted passage. When I get home, I copy the bibliographical details of the works I have consulted into an alphabeticised index book, so that I can cite them in my footnotes. I then cut up each sheet with a pair of scissors. The resulting fragments are of varying size, depending on the length of the passage transcribed. These sliced-up pieces of paper pile up on the floor. Periodically, I file them away in old envelopes, devoting a separate envelope to each topic. Along with them go newspaper cuttings, lists of relevant books and articles yet to be read, and notes on anything else which might be helpful when it comes to thinking about the topic more analytically. [...] ¶ The truth is that I have become something of a dinosaur. Nowadays, researchers don’t need to read early printed books laboriously from cover to cover. They have only to type a chosen word into the appropriate database to discover all the references to the topic they are pursuing. … ¶ Yet as I pick my way through my accumulation of handwritten material, I don’t feel depressed. The thousands of used envelopes themselves give me a good deal of nostalgic pleasure; they remind me of old friends, of institutions with which I have been associated and of the secondhand booksellers who have sent me catalogues over the years.
When I was researching my history thesis, I transcribed excerpts with my laptop, but then printed each on a separate page, stored them in lever arch files, and tagged them by topic with colour-coded labels. [via]
