I thought we might help each other out here and post on-line sources that we have found helpful.
I've been writing a biography of a member of a US presidential family who became a published author after marrying into Russian aristocracy. I found the following sources invaluable:
www.lexis-nexis.com for researching articles in mainstream publications
www.ancestry.com which has passenger manifests which are very useful in tracing journeys. Best information is for US travel of less than reigning monarchs.
www.ebay.com for reference or research books, cheaply. Books are covered extensively in another thread, but I have found ebay to be a terrific source. Books that originally went for hundreds of dollars (like one I bought last week) can be had for $20; books that were originally under $50 go for $5.00 or less. [Plus I picked up a pair of Chanel shoes for $300 (original retail $899) so it's not always about royalty.] For me, it's been worthwhile because when I'm doing research, I scribble all over my books: bend pages, highlight, do margin notes. Having more than one copy purchased cheaply is wonderful.
I post these three just to sort of prime the well. For someone researching an individual, a family or an event for publication, there are a myriad of sources.
I'd like to invite others who have done research and can "vouch for" sources that they found particularly useful to keep adding here, as will I. Some sources are better than others in some area of research, while other sources cover different areas better. It would be great to know which are which.
Come on in, everyone, the water is fine.......
