Hospital library users often use library resources for doing research for scholarly and professional writing projects. Citations and format style for academic papers and publications must often conform to the “APA Style”, found in the Publication Manual of the American Psychological Association. This publication manual is among the pantheon of standard publication manuals on library reference shelves, including the American Medical Association Manual of Style, The Chicago Manual of Style, and Turabian’s “Manual for Writers”. The APA style is prominently used in social sciences and many nursing and allied health publications. Hospital librarians may be asked for advice on formatting manuscripts and citations, and should know more about the APA style, supporting resources, and where to turn for authoritative information on its rules.
