I just searched for info on the Dreyfus affair (France 1894) and thought there'd probably be a wiki link, and yes there was, but there was also an Encyclopędia Britannica link, so I chose that.
Encyclopędia Britannica is a free site and the article that I looked at didn't nominate an author, so I assume that it was written by the Britannica staff Editors.
I don't know how limited the site is for information but as Britannica's reputation goes it's certainly a site that I'll refer to again.
Anyone else used it?
(The book I've started to read is Robert Harris' An Officer and a Spy which uses the techniques of a novel to retell the true story of the Dreyfus affair, a political scandal and miscarriage of justice that in the 1890s came to obsess France and ultimately the entire world. Zola supported Dreyfus and wrote J'accuse which is what I was interested in following up.)
