To make it easier for you to find new and updated material, I’ve added two new features to the science.robertprior.ca web site. The first is this section, where I’ll announce new and updated resources. The second is a date under the download link on a page, indicating when a resource was last changed. Note that resources without a date were last changed before today (October 23, 2013) — it will take me a while to update all the dates.
