Lumen is a project of the Berkman Klein Center for Internet & Society at Harvard University.


Lumen is an independent 3rd party research project studying cease and desist letters concerning online content. We collect and analyze requests to remove material from the web. Our goals are to educate the public, to facilitate research about the different kinds of complaints and requests for removal--both legitimate and questionable--that are being sent to Internet publishers and service providers, and to provide as much transparency as possible about the “ecology” of such notices, in terms of who is sending them and why, and to what effect.

Our database contains millions of notices, some of them with valid legal basis, some of them without, and some on the murky border. Our posting of a notice does not indicate a judgment among these possibilities, nor are we authenticating the provenance of notices or making any judgment on the validity of the claims they raise.

Lumen is a unique collaboration among law school clinics and the Electronic Frontier Foundation. Conceived and developed at the Berkman Center for Internet & Society (now the Berkman Klein Center) by then-Berkman Fellow Wendy Seltzer, Lumen was nurtured with help from law clinics at Harvard, Berkeley, Stanford, University of San Francisco, University of Maine, George Washington School of Law, and Santa Clara University School of Law.

The project receives continued support from various organizations and clinical programs. Lumen has had the privilege of working with the following partners, both past and present:
