The slump in sales of paper-based encyclopedias around the turn of the 21st century hit Kunnskapsforlaget hard, but a fourth edition of the paper encyclopedia was secured by a grant of ten million Norwegian kroner from the foundation Fritt Ord in 2003. The fourth edition consisted of 16 volumes, a total of 12,000 pages and 280,000 entries.[5]
The online edition of SNL was launched in 2000, and had both private and institutional subscribers. The paywall was removed on 25 February 2009, and the online encyclopedia became free to use.[7]
On 12 March 2010, Kunnskapsforlaget announced that they would close the online encyclopedia because of lacklustre sales and failing revenue. It was also announced that the articles would not be given to the Wikimedia Foundation, with chief editor Petter Henriksen stating that: "It is important that the people behind the articles remain visible".[8]
As of 2023, the SNL has around 200,000 articles online, updated by approximately 1,200 affiliated academics. The SNL accepts contributions from users, but all changes to the articles are verified by a topic expert before publication.[12]
