This post: 33 Reasons Librarians are Still Extremely Important - DegreeTutor.com is popular on a few librarians blogs at the moment. I suppose there are a lot of librarians out there who feel the need to defend their existence and this kind of post is an expression of that. The post argues effectively that libraries will always be needed (in the foreseeable future) so by extension, people who run libraries will be needed.

So are librarians feeling under pressure because they feel that their skill set is not widely understood and therefore not valued? Or is it because the required skill set of librarians has radically changed in a short period of time? Perhaps it's to do with overlapping areas with other professions such as IT and education.
