Introduction
The term “bibliography” comes from the Greek words “biblion” (meaning book) and “graphia” (meaning writing). In the field of library and information science, bibliography refers to a list of books, articles, and other information sources related to a particular subject, author, or period. Bibliographies are useful tools for students, researchers, and librarians as they guide users to relevant and credible sources of information.
Definition of Bibliography
According to the American Library Association (ALA), a bibliography is “a list of works (such as books and articles) written on a particular subject or by a particular author.” It includes details like the title, author, publisher, date of publication, and sometimes a summary or notes.
In simple words, a bibliography is a well-organized list of sources that someone can use for further reading or research.
