After reading many of these posts, I just decided to add my idea. I take a recipe card (3x5) and write the topic on it and the page I have finished reading. Then if I don't get to read all the posts, I know where to pick up. When I go back, I start on the page I left off and then cross it off when I move on. When I have to quit reading, I write down the page number again etc. I have about 3 topics on each side of card. Some of the posts are over 50 pages long so I have not yet come to the end but at least I know what I have read. Hope that is clear. Some days I have the compulsion to sew instead of reading all these wonderful topics. :-) Great thread!
