Technically, the term "librarian" refers to an individual who has obtained a Master's Degree in Library Science or Information Science, but is increasingly used to refer to any of a number of professionals and para-professionals employed in a library
. The main function of a librarian is to connect individuals (patrons or customers) with information
, whether found in print, audio, video, or other (i.e. online) formats.
