Q: “How do you go about researching content for your textbook?”

A: Janet Belsky, author of Experiencing the Lifespan, 2e (2009):

“I go to a library database where I can get every single article on the topic I’m writing about in every journal in my field. If I am updating a book, I will only look for articles that were published from the time of the last edition to the present. This strategy gets me about 100 or 200 new articles for each chapter. I do a cursory look at everything, but I won’t need to read all of those articles.
