PennTags is a social bookmarking tool for locating, organizing, and sharing your favorite online
resources. Members of the Penn Community can collect and maintain URLs, links to journal articles,
and records in Franklin, our online catalog and VCat, our online video catalog. Once these
resources are compiled, you can organize them by assigning tags (free-text keywords) and/or by
grouping them into projects, according to your specific preferences. PennTags can also be used
collaboratively, because it acts as a repository of the varied interests and academic pursuits
of the Penn community, and can help you find topics and users related to your own favorite
online resources.
PennTags was developed by librarians at the University of Pennsylvania.
And this is just the tip of the iceberg; annotations could include sound and video clips, links to other suggested resources ("see also..."), hyperlinked search strings for the library catalog, WorldCat.org, Diigo, Google, or other sources, plus about a zillion things that I can't even think of.
