Libraries aren't baseball teams, but if they were, mine couldn't compete with others in the area. We don't have the resources. And this is where moneyball comes in. There are market inefficiencies for libraries, that librarians and library staff should be exploiting them. A couple stand out.
- Data on library activity
- Open-access journals
Second, and also free, librarians should be educating patrons (and faculty and students, in that order, if you work in an academic library) about the free scholarly resources that exist online. In particular, I'm thinking of the Directory of Open Access Journals. Compared to the cost of databases that aggregate journals and their articles, open access can't be beat on price. They don't cost libraries a thing. They are priced inefficiently, but never mind that; get those DOAJ titles into your catalog, or link to it from your library's homepage, or promote it on a blog, or tweet it, or all of the above.
That's two to start with, but I'm sure there are more out there. Let's start a discussion, shall we?
* For those interested in baseball, the underpriced skills mentioned above were the ability to get on base (as opposed to the ability to hit for high average), defensive excellence (which also plays a role in the recent success of the Tampa Bay Rays), drafting pitchers with college experience, and utilizing statistics called sabermetrics.
And yeah, I'm going to link to Wikipedia. I vetted both those entries and they look fine to me.
