A relative was great about sending me stuff while she was actively researching and I really appreciated it. She always indicated the volume number of the courthouse book and the page number of the information. The problem is that she sometimes made up book titles and occasionally they aren't accurate. She extracted accurately but, sometimes left out key details. If you are using Family History microfilm of original records, look at the "title sheet" that starts each record and use that for your title if you don't know what the book is.
You never know, you might want to go back some day and review it yourself.
