I do a similar thing for books. A lone dot on the spine means I read it carefully enough to take notes on it.
I like to write commentary in the margins, so the dots help me know which books are "devalued" and which are fine to donate or loan out to others.
Multiple dots are an indication I return to a book often. Each time I re-read I take notes in a different ink color and try to record the date in that ink color in the front matter.
