McGraw-Hill is well-known for its strength in academic (educational and professional) content. It is partnering with Follett to expand sales of ebooks into K-12 schools.
This will have a good impact on authors. The availability of ebooks allows for more readers to find authors they might otherwise never hear about. Ebooks also provide publishers with a way to monetize their backlist, which means that authors whose works are out of print can derive fresh income when their books are re-released in electronic form.
The disruption is doing its job. Things are looking up for publishers and for authors, and this is just one example!
