The Library of Congress, like many cultural heritage organisations, faces a number of challenges as it seeks to increase discovery and use of its collections. A major concern is making historical and special format materials easier to find in order to be useful for educational and other pursuits. At the same time, resources are limited to provide detailed descriptions and historical context for the many thousands of items in research collections. The Library also faces competition for the attention of an online community that has ever-expanding choices of where to pursue its interests.

One solution worth exploring is to participate directly in existing Web 2.0 communities that offer social networking functionality. Reaching out to unknown as well as known audiences can attract more people to comment, share, and interact with libraries. Taking collections to where people are already engaged in community conversations might also encourage visits to a library's Web site where the full wealth of resources are available.
