I was working with tax lists while at the Family History Library in May. In my excitement over finding relatives in a 1831 tax list, I almost neglected to copy the headings for the tax lists. The headings were on the first page, not the page I copied. Fortunately I copied the page with the headings as well. If had just copied the page with the names I wanted, I would have been out of luck. The page with the names I need is posted here (without headings)
Always make certain the headings are on the page you have or get them if they are on a previous page. It may be a cliche, but haste can make waste.
