Not a new topic, but being raised again and again....
Here it is raised because of dwindling textbook revenue.
"Will librarians go the way of the soda jerk, telephone operator and travel agent? A new study suggests it's already happening. (Will digital media push librarians to the brink of extinction?)"
"According to a new study of the textbook market by Bowker, library information science textbooks generated about 30% less revenue in academic year 2011 (ending in Spring 2011) than in the previous academic year. It topped the chart of “declining” disciplines at this morning’s Book Industry Study Group higher education publishing event in New York."
