Laut dem Artikel “What Exactly Does a Librarian Do?” kommt es darauf an, in welcher Art von Bibliothek sie tätig ist. Für “School Librarians” z.B. gilt (im englischsprachigen Raum):
“School librarians are specially trained to work with primary and secondary students. Also known as “school media specialists”, these librarians ensure that elementary, middle, and high school students are able to effectively use library resources to aid in their studies and their interests.
Another major role that school librarians play involves collaborating with teachers in creating lesson plans. School librarians are especially helpful in introducing new technology into teaching strategies and helping teachers find good material to include in classroom instruction.”
