Perma.cc is a web archiving service for legal and academic citations founded by the Harvard Library Innovation Lab in 2013.{{cite magazine | url=http://www.newyorker.com/magazine/2015/01/26/cobweb | title=What the Web Said Yesterday|first= Jill | last= Lepore | authorlink=Jill Lepore | magazine=The New Yorker | date= 26 January 2015 | accessdate=27 January 2015}}
Concept
Perma.cc was created in response to studies showing high incidences of link rot in both academic publications and judicial opinions. By archiving copies of linked resources, and providing them with a permanent URL, Perma.cc is intended to provide longer-term verifiability and context for academic literature and caselaw. Perma.cc is administered by a network of academic and government libraries.
In 2016, Harvard received a $700,000 grant from the Institute for Museum and Library Services to expand development of Perma.cc.{{cite news|title=Harvard's Perma.cc receives grant to expand its tools for saving sources on the Web|url=https://today.law.harvard.edu/harvards-perma-cc-receives-grant-expand-tools-saving-sources-web-2/|accessdate=February 24, 2018|work=Harvard Law Today|date=April 14, 2016}}

Perma.cc initiates page saves by user request only, it does not crawl the web and save pages like the Wayback Machine. A user account is required to save a page. Its target audience are organizations such as libraries, academic journals, law courts and school faculty. It provides support for organizational membership and administration of user accounts. Metadata such as notes can be added which are viewable to members within an organization. Pages can be made public or private within an organization. In 2017, Perma.cc added individual accounts limited to 10 free page saves per month, and commercial option for non-academic organizations to create institutional accounts.{{cite web |url=https://perma.cc/sign-up |title=Perma.cc for individual users |author= |date= |accessdate=March 11, 2017 |quote=Anyone can create a free, individual Perma.cc account, which will allow you to create ten links per month.}}{{Cite web | url=https://perma.cc/terms-of-service | title=Websites change.
