These are large format bound volumes of the official lists that were posted up for the public to see - 3 times a day - forenoon, noon and afternoon - at the close of the trading session in the call room at the Sydney Stock Exchange. The closing prices of stocks and shares were entered in by hand on pre-printed sheets.
The volumes have been digitised, resulting in a collection of 70,000+ high resolution images. You can browse the details of each volume using this notebook.
I’ve been exploring ways of getting useful, machine-readable data out of the images. There’s more information about the processes involved in this repository. I’ve also been working on improving the metadata and have managed to assign a date and session (Morning, Noon, or Afternoon) to each page. We these, we can start to explore the content!
One of the notebooks creates a calendar-like view of the whole collection, showing the number of pages surviving from each trading day. This makes it easy to find the gaps and changes in process. #dhhacks
