I have had the pleasure of working with several scholars over the years on research that has resulted in publications (journal articles, books, reports). A few of those scholars have been gracious enough to acknowledge my help in print — most recently, Andrea Henderson acknowledged my help in designing the survey for the incredibly important report: Dual Career Academic Couples: What Universities Need to Know.
Since most academic libraries and librarians consider their central mission to support the research and teaching of their institution; an acknowledgment in published research is a pretty tangible and important measure of that aspect of a librarian’s performance. I know it is not the only measure, but it is a nice public one, and it is one I think we should “brag” about. I know I would want to know if someone I was considering for a reference librarian job had been acknowledged by scholars in their published works.
So, I think librarians out to publicize their acknowledgments. Libraries could create web pages full of librarian acknowledgments, and individual librarians could add an acknowledgments section to their CV.
