The term networking often invokes feelings of discomfort among genealogists (and nearly everyone else). However, talking with those around us at our local genealogy meetings, asking questions on social media, and looking for opportunities to share and learn from others, doors to resources and methods you didn’t know existed will be opened.
Networking used to be a scary term for me too because I am an introvert. Then I became caught up in the excitement of sharing with and learning from others and I didn’t even realize I was networking. Talking to the person standing next to me at a history event connected me with a fellow genealogist who is a librarian and we will soon be meeting to swap resources about the history of medicine and genealogy. Another genealogist knew I was interested in medicine and directed me to a cookbook with medical recipes she had found at a repository. That became the primary source for my thesis.
An easy place to start is social media. I have found countless new (to me) resources via Facebook. I see what other people are posting on their feeds and interact with them. I also post on my feeds items of interest to me. Because people know my interests, they will often contact me with an article or resource they came across that they thought might interest me.
What success stories have you had with networking?

I am very fond of networking through some of the Facebook group pages. Through one, I have learned more about finding my Netherlands ancestors. Through another, I have been learning to refine my techniques (and recently learned of a repository I will need to have searched); that group and another have taught me many ways to improve the physical organization of my data (including storing sources).
