Staffing situations vary from library to library based on a number of factors including population served, budget, and organizational structure. So who gets to staff programs? YALSA’s guidelines lay out a number of considerations to take into account whenever making staff and volunteer assignments for a program, no matter our size or structure. Points 6.3 and 6.5 in particular consider the different roles that staff and volunteers take.
6.3: Consider which tasks are best suited to librarians and which are more suited to paraprofessionals, community partners and mentors, adult volunteers or Friends of the Library, and teen volunteers and participants.
With any program, someone needs to take the leadership role and accept responsibility for everything (the good and the bad) that comes of it. I find this is most often the person (usually a librarian) who pitches the program, and who believes in it enough to carry through with it. Whether hiring a presenter or relying on a crew of regular volunteers, the program leader needs to know (or find how to find) the answers to any question anyone may have about it from the time it first goes on the program schedule to three weeks afterward, when someone calls to ask when the next one will take place. The librarian leading a program is also most often the person charged with enforcing the rules as in, “Sorry, this a teen program for teens only.”
