The New York Times, Los Angeles Times, Chicago Tribune and Huffington Post are part of the initial launch, according to a press release.
Websites Mediabistro and TechCrunch have also signed up for the new version of Scribd's document reader, which has been made available for free.
The technology will allow journalists to convert source documents from a range of file types into web documents that can be shared and embedded.
Supplying original documents could increase readers' time on a page and encourage transparency and proper source attribution, Scribd said.
"The concept of news and journalism is quickly evolving. With this launch, Scribd is giving news organisations a way to present their source material as an important part of the story, both on and off their websites," said Trip Adler, CEO and co-founder of Scribd, in the release.
It is also hoped the inclusion of each news site's logo or masthead on the reader will help promote the organisation wherever the documents are shared online.
The reader also allows users to share links to the source material via social media sites.
Other news organisations can apply for their own branded Scribd reader for free on the company's website.
Scribd, which has become popular as a book and magazine sharing platform, has already become a valuable source of news leads for journalists. The documents for Journalism.co.uk's report into the Financial Times' planned newsroom changes were shared publicly via the site.
