When the list overtakes the list items

This is how much I love keeping lists:

I maintain a running log on my blog of books that I've read during the year. I just finished reading Glimmer Train 74 (that's a literary magazine, in case you're not familiar), and even though it was 200-some pages long, I'm peeved that I can't add it to the list because it's not a book. I mean, if I can't list it, it's like I didn't really read it, isn't it?
