BookmarkPress

BookmarkPress is an extension of the Press This function of WordPress. BookmarkPress creates a separate post type (so they are stored differently) and also has a framework into which plugins can be added to expand its functionality.

BookmarkPress is used for an online course for Of the Common Law (http://ofthecommonlaw.com/links-library/), and by the University of London on their MOOCs (http://links.laws.londoninternational.ac.uk/) and on OpenJoyce (http://openjoyce.com/sites/library/)
