I read Scott Plutchak's blog post Looking for a Ladder, and I thought it was one of the best recent posts on change and librarians. Specifically on librarians looking to start a change within their institution.

I might just make one little addition to his already great post, for people who are interested in changing things up a bit. Don't be afraid to start small. In fact I highly encourage starting small and perhaps continually doing small changes. An avalanche often starts with just a little bit of snow slipping down a slope.
