Most recently, Malamud has set up the nonprofit public.resource.org, headquartered in Sebastopol, California, to work for the publication of public domain information from local, state, and federal government agencies. Among his achievements have been digitizing 588 government films for the Internet Archive and YouTube, publishing a 5 million page crawl of the Government Printing Office, and persuading the state of Oregon to not assert copyright over its legislative statutes. He has also been active in challenging the state of California's copyright claims on state laws by publishing copies of the criminal, building, and plumbing codes online.

He has also challenged the information management policy of Smithsonian Networks, convinced C-SPAN to liberalize their video archive access policy, and begun publishing court decisions.

In 2009 he proposed himself, through the [http://yeswescan.org/ "Yes We Scan"] campaign, as the [[Public Printer of the U.S.]], the head of the Government Printing Office. He is currently leading an effort, under the banner of [http://resource.org/law.gov/index.html Law.gov], to bring online all primary legal materials (including legal codes and case law) for open public access.

An early Internet pioneer, he is the author of many early books about networking such as Analyzing Novell Networks and DEC Networks and Architectures.
