You may have seen this campaign back when it launched in September 2013, in honour of National Library Card Sign-up Month. Pinal County Library district produced 30 unique images in the style of old Penguin and Pelican book covers, and released one a day. Each highlights a different benefit to becoming a library member. There’s a very thorough write-up on the Pinal County Library blog. Great idea; it caught the eye of Cory Doctorow on Boing Boing, which is always a plus.

My favourite: Read to the Dog
