This article is not directly related to information literacy but I did find it of interest to reference work. The article is Students' Perception of the Impact of User Education on the Use of Reference Resources: An Iranian Experience and it was written by Mahdi Mohammadi, Alireza Isfandyari Moghaddam, and Mehri Ezadi Yeganeh. The article appears at Library Philosophy and Practice.
From the abstract:
This research examines students' familiarity with reference resources as well as the necessity of providing user education based on students' point of view. A sample of 351 students were given a questionnaire of 22 questions. Findings show that students find user education necessary and beneficial, and that students would like to see expert and professional librarians in the reference department.
I do not find these results surprising at all. Patrons do prefer to deal with librarians if they are looking for information in a library. They will choose a librarian over a student worker just about every time. However, outside of identifying obvious student employees, patrons have trouble telling support staff from librarians. This is a good argument for name badges with titles.
