“Library anxiety” was identified thirty years ago when Constance A. Mellon of East Carolina University published her paper, “Library Anxiety: A Grounded Theory and Its Development,” [College & Research Libraries 47.2 (1986): 160-165. <http://crl.acrl.org/content/47/2/160.full.pdf>], describing college students feeling intimidated, embarrassed, and overwhelmed by libraries and librarians. Library literature has been enhanced by this topic since then.
The anxiety appears to be more common among freshman students. This phenomenon ascertains the importance of library instruction for first-year undergraduates, as well as calls for user-friendly learning environment. A recent report on Columbia libraries is fun to read: “The Strange Affliction of ‘Library Anxiety’ and What Librarians Do to Help” <http://www.atlasobscura.com/articles/the-strange-affliction-of-library-anxiety-and-what-librarians-do-to-help>
