Individual Past Lessons

Hello. After reading an article, I tend to download it so I can put it on my iPod. However, I found that while I understood the article at the time, after it has been awhile, I can quite catch everything that is being said. I would like to look at the text again, and while I have found a few of the articles, some that have downloaded without names, have been harder to find. Is there a place where I can get a record of just the individual listening activities that I have completed/used?

Regards and thanks.
