Database Marketing

As our library district seeks to save money, databases are being discontinued and reevaluated on a regular basis. Do we really need more and better databases? Which ones are essential? Many patrons are not aware of these databases, how do we market them online and in the library, or on the web and in print etc.? Even many of our staff members are not aware of the databases on our website, is this because they are not that useful? I find many of them very useful, I wish we had more but the trend is going in the other direction. What do we do now?
