If you haven't tried Smore to create your library newsletters, you should! Great tool, easy to use, and gives you stats on how many people have read your newsletter, plus how much time they spent on it. Here's an example of my latest newsletter. Oh and they also make it easy to share your creations, embed on a website, email to a list, or share the link in a tweet. Seriously, what are you waiting for? Tell people about your wonderful library students.
