I have been completely distracted this morning.
My main post today was Round the history blogs 9 - Footnotes, presentism and soldiers of fortune. In searching, I found this post: Tracking the trends via Google’s New Book Database.
Please visit. There I found the latest Google tool, one that allows you to find out how many times words and phrases have been mentioned in books included in Google books.
The following graph shows how many times the word feminism has been mentioned in books on the Google system. You can actually see the rise and then decline of feminism in the graph. Do play. I suspect that you will waste many pleasant hours!
