While Reading Articles Published in Refereed Journals About Her Research

While reading articles published in refereed journals about her research topic,Georgia repeatedly comes across references to a series of studies by one particular researcher.She's unable to find those references in the collections of her university library.Her best plan of action would be to:

A) Summarize the research,noting the references were "cited by" the articles she did read.
B) Include the references in her reference list but not cite them in the text.
C) put in a request through the library loan program.
D) Search the Internet for copies that may have been posted.
