Some readers have expressed concern regarding the decrease of the frequency of my posts during the last two years. As I explained in June 2015, my research is very time-consuming and I'm not getting paid for my writing on this blog. If readers are not willing to support my work with donations, this blog will have to be discontinued. I would also like to state that questions and inquiries submitted via e-mail cost time to be answered. And since time is not free, requests can only be answered if they come with a donation.
On the occasion of a recent copyright infringement, I have to point out once again that all the digital copies of historical documents on this blog (unless otherwise indicated) are first publications. The unauthorized use of these files, whose creation is based on a lot of personal work, represents a violation of copyright. While most archival documents are in public domain, their digital copies are not.
