Robots Are Our Friends
For a variety of reasons cultural heritage organizations often have robots.txt documents that restrict what web crawlers (aka robots) can see on a website. This is a bad thing because it means that the content that libraries, archives and museums are putting online becomes virtually invisible to search engines like Google, Bing, Yahoo, is less likely to be shared in social media sites like Facebook, Twitter, Pinterest and stands less of a chance of being incorporated into datasets such as Wikipedia. The Robots Are Our Friends campaign aims to help promote an understanding of the role that robots.txt plays in determining the footprint our cultural heritage collections have on the Web.

- Collection Achievements and Profiles System and DPLA Crawler Services
