In contrast to fanfiction on Archive of Our Own, published books seem to be categorized more by genre. For instance, this screenshot was taken from the Amazon homepage for books, and shows some of the main categories by which one can sort for books on this site. Again, it seems more genre-based, including tabs like “Romance” and “Mystery, Thriller, and Suspense.” As shown in the previous examples, fanfiction does not necessarily sort by genre; at the very least, the “genres” it uses are different and more expansive. Furthermore, Amazon does not seem to give any tag options with the intention or ability to exclude them, like how fanfiction does. One last thing to note about book tagging is that it is much more rigid, with each book having to fit into a certain preexisting genre. On Archive of Our Own, the author could tag their work with absolutely whatever they want, which could lead to a “messier” tagging system, but also allows more flexibility for the writer to tag what might be relevant. In contrast, with books, the writer might not even have any control over how their book is classified. If the author is not classifying their own work, others’ perceptions of the text could impact how it is classified. Both the fanfiction and book methods of classifying and sorting texts may be useful, and both may have different drawbacks, depending on the specific reader or author and what their goals are. When you are looking for a text, what would you prioritize? Do you think you would prefer either of these tagging systems, or do you like elements of each?
