Distribution of written documents from articles to books typically does not involve paper and ink.
Grader A: partial
Articles moved online by 2009: news, journals and reports were routinely distributed as web pages and PDFs. Books did not: e-books were about 3% of US book sales in 2009 and passed hardcovers only in Q1 2012. The claim covers 'articles to books', so it was half true in 2009 and more true in 2012-2014.
Test: E-book share of US book sales: 3% (2009), 8.5% (mid-2010); passed hardcover in Q1 2012. Article distribution online: majority for journals and news by 2009.
Grader B: partial
The claim is split. Articles: by December 2010, 41% of Americans named the internet as their main news source, against 31% for newspapers. Books: e-books were about 3% of US book sales in 2009 and 8.5% by mid-2010. E-books passed hardcovers only in Q1 2012 and never became the typical form. Distribution without paper was typical for articles, not for books.
Test: Test: over 50% of written-document distribution is non-paper. News: internet 41% vs newspapers 31% as main news source (2010). Books: e-books about 3% (2009) and 8.5% (mid-2010). Books do not pass 50%.
