Have you just started your PhD? You might be interested in going along to a British Library Doctoral Open Day. Here's what they offer:
"Our Doctoral Open Days are a chance for new PhD students to discover the British Library’s unique research materials. From newspapers to maps, datasets to manuscripts, ships' logs to websites, our collections cover every format and language and span the last 3,000 years.
You will learn about our collections, find out how to access them, and meet our expert staff and other researchers in your field. The events are aimed at first year PhD students who are new to the Library."
