I've been doing research for my current work in progress. As I write, when I don't know something or need a fact check, I make a note in the margins and keep typing. with this book, the margin questions started to pop every paragraph. I knew I had to step back and take some time to figure out the details. I've chosen a part of the world I am not as familiar with: the Middle East. My husband and his family lived there for a number of years and they have been great providing information, books, and personal anecdotes about their experiences. Internet searches have helped a little too. I've having fun with this book and learning a lot, although the extra research has slowed the pace of my writing a bit. Once I hash out the details, I hope the flow of words will increase. What are your favorite ways to research? Do you research your book first and then write, or write and research in tandem?
