Step-by-step explanation:
To find all the documents about Canadian author Margaret Atwood in the library's online public access catalogue, you would typically start by entering her name in the search bar. Author search is generally used for fiction materials, since they are filed by the author's last name. However, for a more comprehensive search that includes non-fiction publications like literary criticisms, academic papers, or other materials about Margaret Atwood, it is helpful to use the Library of Congress Subject Headings (LCSH) or keyword searches that target specific terms related to Margaret Atwood. Since Margaret Atwood is a famous Canadian author, you may also consider using terms such as "Canadian literature" or "literary criticism" in consort with her name to ensure a broader and more targeted search. If you are using a college library, such as those within the State University of New York library system, you may have access to robust databases like Academic OneFile from Gale or Academic Search Complete from EBSCOhost, which can provide a wealth of materials on the author. Remember that a reference librarian can be very helpful in assisting you with constructing effective search terms.
