 When you write a paper in Classics, you will most likely be writing a research paper and use a variety of sources, including ancient cultural productions (e.g., ancient texts, artifacts, etc.), as well as modern scholarship that discusses these ancient sources. Make sure you check out our sections on [Primary Sources](/primary-sources), [Secondary Sources](/secondary-sources), [Reference Sources](/reference-sources), and [Commentaries](/commentaries) to understand how to effectively use each category.

 [Hollis](https://library.harvard.edu/services-tools/hollis) is Harvard Library's catalog. Search HOLLIS for books, articles, media and more.

 [InterLibros](https://guides.library.harvard.edu/interlibros), the Harvard Library Research Guide for Classics, Byzantine, & Medieval Studies, is a good starting point for Classics-based research.
