Most people have seen the photo sharing site, Flickr. Many libraries are using Flickr as another PR tool to attract users. Flickr can be used to show past library events and speakers, and it can also be used to showcase teaser material.
As with other Web 2.0 tools, community participation can be a key part of the experience. Allowing users to tag and comment on photos makes it a participatory experience instead of just a click-through.
Special collections can be highlighted with teaser content that leads users back to the main website for the full digital collection.
Libraries can connect with other libraries who may have related collections. This connection helps point patrons to additional content.
