You’ve done your research. You’ve written your manuscript. You’ve sold your book. No need to ever think about research again, right?
Wrong, wrong, wrong. In the last month, I’ve combed through historical maps of Kansas (I’ve had to move May’s home; my original setting happened to be smack dab in the middle of a cattle trail), read up on the differences between the short grass and mixed-grass prairies, double checked the process of building a soddy, and Googled every frontier town along the Kansas Pacific Railroad.
Just like revision, research often needs to be on-going.
