Well back to the title of this post. Having done a number of research papers during my tenure as a student and a teacher in training, I cannot emphasize the importance of reference librarians. Their acuity for detail and the vast quantities of information that they seem to absorb daily is astounding. However, the availablity of this resource is often limited to face 2 face meetings and email. As Web 2.0 technologies often do, an opportunity for a new paradigm in this arena has taken form and the tool is Twitter.
Now I have not written a research paper in a few years, so my reliance on reference librarians has been minimal but for several months now, I have relied heavily on my PLN via Twitter to gather information both actively and passively. Everyday my PLN provides me with some pearl of wisdom or a response to a query and I can only hope that I am able to do the same for those who have included me in their PLN.
Nevertheless, because I am Still Learning, I am grateful to have my very own PLN/Web 2.0 reference librarian.
