Philologists engage in research that seeks to explain and interpret literature in order to increase general literary understanding and interest.
Philologists can work in many diverse fields. Examples include teaching at all school levels as well as working at science and research institutes, advertising agencies, book publishers, libraries, the media, and theaters. The theoretical knowledge of philologists is also useful in writing and publishing.
Philologists often specialize in certain branches of literature, such as individual periods, genres, or authors.
