The National Library of Australia has been given a funding boost to upgrade its popular digital resources portal Trove, following doubts about its future.
The library had stopped funding the digitisation of newspapers and other content in July, after cuts through the government's efficiency dividend were announced in late 2015.
It had also relied on contributors to pay for the uploading of new documents if they wished to expose their collections through Trove, a Senate estimates committee was told.
But the mid-year budget review, released on Monday, included $16.4 million over four years for the library to digitise material and upgrade the Trove system.
The funding will be taken from the Public Service Modernisation Fund.

Trove is the commonwealth's fourth most heavily used website, behind the Bureau of Meteorology, Centrelink, and the Department of Human Services, with more than 55,000 visitors a day.
The 2015 mid-year budget review included an efficiency dividend for cultural institutions totalling $36.8 million over four years.
