As many articles and reports are listed by author's last name and first inital, and most of those are not extremely unique names, these organizations have made it their mission to create unique identifers for the public identities of individuals to prevent confusion over people with the similar or even the same names.
"WorldCat Identities has a summary page for every name in WorldCat (currently some 30 million names) including named persons, organizations and fictious characters. The pages include information derived from WorldCat and other sources (VIAF,FAST) plus with unique data derived or created through a variety of special processing activities (e.g., WorldCat Identities provides statistical data about how widely held a work is). A typical WorldCat Identities page will include a list of most widely held-by-libraries works by and about the identity, a list of variant forms of name the identity has been known by, a FAST tag cloud of places, topics, etc. closely related to works by and about the person, links to co-authors, and more."
