I admit when I first started researching my family history I wasn't good at citing my sources. I was more interested in getting names and dates on my family tree. After a few times of wondering, "where did I get that information from?" I started doing a better job. I also switched to Roots Magic genealogy software and wanted to do a good job with sourcing. Then, I figured out I was invariably forgetting to get one piece of information from the source. Usually, the page number! So, I developed a source summary sheet to help me record the information. I use this mostly when I go to libraries. I have used it with google books and the books on ancestry.com too. I usually write the library name at the top of the sheet. I even use it to record sources I have looked at and didn't find anything in. In that case, I usually put an O with a line through it in the page # column. It has been helpful when I go back to the library, I know what I have looked at. I keep the filled in sheets in a file folder alphabetically by repository name. A completed sheet is below. Do you have an easy way to keep track of your sources? Share it in the comment section.
