The increased use of automation means that librarians must be technologically savvy, but by the same token their clerical work has decreased significantly. PR too Librarians are also public relations representatives, since more than half of their days are spent interacting with people. They must constantly maintain a helpful and friendly countenance, no matter how demanding or difficult the library patron. Librarians are instructors as well, assisting patrons with accessing data through the computer systems. Not just at school Librarians can actually work in a variety of settings.
Many librarians prefer the relative autonomy and academic setting of public libraries.
Librarians in school libraries must be certified as Librarians, because they teach students how to use the library and sometimes prepare readings and lessons. They also help Librarians obtain instructional materials and assist students with special assignments. Some librarians work in government libraries, museums, and laboratories, where their work is almost all research-based. For librarians in the private sector, who work with specialized medical, law, or corporate libraries, the pressure is higher, but so is the salary. Since libraries are open on weekends, librarians' workweeks often extend past the usual five days, and they work many holidays as well.
