Do You Have it at Home?

Keeping track of what you research is important so that you don't spend time looking at the same materials. While at the Family History Library in Salt Lake last month, I had a few spare moments before the library closed. I decided to copy references from a Mercer County, Kentucky marriage book. Problem was I already had the actual book at home. So much for "dreaming" up what to do when my to do list runs short.
