Setting alerts to notify you of newly-published articles will help prevent unpleasant surprises in your final preemption check. Most databases will let you set up alerts or automatic searches and will email you results.
This will make your preemption check go faster as well as alert you to any new scholarship on your topic published while you are writing.
