A succinct list of things that all librarians should be able to do/know is available at http://www.libraryman.com/blog/101rtk/. All the normal bases are covered, however some of the links are to pretty basic resources on the subject, but considering the need for brevity it is still a good heads up or first look at these things for beginners. Though actually if you are already a librarian, you really should have caught up on all or most of these tools/skills a while ago.
Brought to you by Michael Porter & David Lee King the site also has this very nice video (below) on the frontpage reminding us that we have to change library services with the times to remain relevant, this valuable lesson is delivered in the form of a lively succession of pastiches of ‘pop’ videos. The site also has a set of essays, which includes a video essay by Australian Kathryn Greenhill at http://www.libraryman.com/blog/?page_id=423
