From The Chronicle of Higher Education:

Attention spans are short. E-readers are plentiful. Digital delivery is fast and convenient. How can university presses turn those facts to their advantage and attract readers who want bite-sized morsels of content?

Princeton University Press is about to test one approach with a new, e-only series. Called Princeton Shorts, it debuts November 9.

The article explains that Princeton Shorts will not be new material, like Kindle Singles; rather, it will be excerpts only of backlist material from Princeton University Press.  The full books will be available through Kindle and Google Books.

Princeton University Press considers this an experiment, hoping the ebook excerpts will drive customers to purchase the full books.  Other university presses will be keeping an eye on the experiment’s progress, as many of them are studying new ways of presenting their content, including schemes like selling textbook material on a chapter-by-chapter basis, based on class curriculum and assignments, and giving partially-loaded reading devices to students.
