Generally, I try to make my blog fairly accessible to people of all disciplines, but I have to admit this one is pretty History orientated.
When I did my internship at IHR over the summer I was asked to write a blog about how I found their Connected Histories search engine, which looks through a number of different archives all so you don’t have to!
Here’s the link to the blog post. I’d definitely recommend reading it/using the website. Have fun.
