Non-fiction can be examined on both micro and macro levels. As regards the former, the focus can be on ways of expression, narrative techniques or style in individual works. As regards the macro level, the focus can be on a certain genre (e.g., textbooks, cookbooks, biographies), its development and variance, or status in the community. All of these are topics for theses and dissertations, as well as course assignments.
In addition to books and non-fiction literature, authors and their activities, as well as those of the readership, are examined.
Non-fiction literature has been primarily studied through the methods of text and discourse analysis, but perspectives of the sociology of literature are also possible. The scope is constantly expanding, since changes in the publishing industry are creating new topics for research. These include the characteristics of and differences between printed books, e-books and online publications, the practices of writing and reading related to various publication platforms, as well as economic and copyright issues related to books. Such perspectives are multidisciplinary in nature.
