Without doubt, librarians have been around for centuries. Different eras, differnet centuries bring along with them differenrt information. Consequently, there is need for different skills if one desires to acquire information.
In the 21st Century, dominated by both technology and the proliferation of information in an unprecedented manner, the main issue is of being "an information literate person".
The issue is not one of access. This does not mean that one need not learn digital skills. However, the real challenge lies in the type of information which exists. Not all information is correct and not all that is found online is acceptable or good enough to be used and shared.
Librarians are the persons who are trained in information handling, ethics, and a variety of other skills, such as digital, among others. They are the ones who guide students, teachers & parents into the information paradigm in order to identify, select, evaluate, use effectively and ethically and finally present information in an appropriate way.
Therefore, librarians are not just librarians. They have different roles to play. They support teachers in their subject, assist students in their information quest and help parents where lack of skills are present.
Librarians need to show leadership among other things in their role as educators.
