I'd like to point you all to a thought-provoking post over at In the Library With the Lead Pipe blog. Emily Ford started a good discussion on the word and idea of "outreach" and titled it "Outreach is (un)Dead."
A tiny piece from the post:
Kill your notion of outreach. We should demolish the body of outreach, but keep outreach activities alive. We should disallow outreach a separate body, but fold its spirit into our daily work and activities, for it is this spirit of work that is the very kernel of what makes a library.
To understand, you need to read the whole post. And the 20-some comments add a lot to it. What's your definition of "outreach" and "marketing"? Do they happen in a coordinated, useful fashion in your organization? Go contribute to the discussion!
