For $20 I was able to have 1,000 cards printed with the web addresses for our media center's web site, blog and Pinterest page. I'll be distributing these cards to parents at our annual Back-to-School night and to my students during their initial media center visits. In one small 2x3.5" gesture, we're promoting the school, furthering the image that teachers are professionals and saving trees. (Last year the language arts teachers and I sent home a newsletter, waaay too much paper.)
There are several sites where you can find easily customized templates and create business cards for your media center or classroom. I chose this one from Vistaprint as it incorporates our school colors of orange and black. My principal was impressed when I presented her with one and I'm excited to get feedback from students and parents, though the true test will be the amount of traffic on the pages listed.
