Libraries offer a great deal of information about careers and job training. Begin by searching the catalog under "vocations" or "careers" and then look under specific fields of work that match areas of interest. For instance, those who like working with animals can find descriptions about the work of veterinarians and veterinary assistants, zoologists, animal trainers, breeders, groomers, and others whose occupations involve working with animals. Trade publications and magazines describe and discuss many kinds of work in various fields.
