DCC is a platform for peer-reviewed and edited commentaries on Latin and ancient Greek texts. It is hosted at Dickinson College in Carlisle, Pennsylvania. The commentaries and other resources are created by scholars from all over the world. Contributors include commentary authors, an editorial boardsecondary teachersstudentscontent editors, and other scholars. Along with annotated editions DCC publishes Ancient Greek and Latin grammars and vocabularies, including the Core Vocabularies (translated into various languages, including Chinese and Arabic) and running vocabularies on each text. The commentaries also incorporate audio and video elements, annotated images, and interactive and static maps. Funding comes primarily from the Roberts Fund for Classical Studies at Dickinson College.

The project began in 2011. Its digital editions have been praised in reviews for their scholarly quality, interpretive richness, and pedagogical utility (Mahoney 2014; Johnson 2014; Stem 2016; Bustos de Lezica 2017). The site analytics show continual steady growth in use. In 2023 the site had 1.6 million total page views. It is used at universities (e.g. UCLA, and the Universities of Virginia and Iowa) liberal arts colleges (e.g. University of Richmond, Haverford), and at many public and independent high schools. A typical testimonial from a high school teacher: “I’m discovering all kinds of wonderful resources to teach Caesar. Yours is at the top of my list – my students and I LOVE it and find it immensely helpful. I just wanted you to know how much I appreciate all your hard and meticulous work. It makes my work easier and far more interesting!” A university instructor, speaking in a review of the DCC edition of Cornelius Nepos' Life of Hannibal, commented, "As a pedagogical platform for teaching Latin with digital materials, this text is visionary in its design."

The commentaries are peer-reviewed, citable scholarly resources, licensed under a Creative Commons Attribution-ShareAlike License (CC BY-SA). The Project Director is Christopher Francese, Asbury J. Clarke Professor of Classical Studies at Dickinson College. Ryan Burke built the site in Drupal 10, DXPR theme (based on a design by Chris Francese and Chris Stamas) and continues to maintain it.


DCC aims at a readerly approach, and one responsive to the needs of readers, teachers, and students.

  • Texts are presented in a clean, readable format, with custom-authored or edited notes, specially selected images, new maps, and original audio and video content. 
  • Core vocabulary lists define the most common dictionary headwords (or lemmas) in ancient Greek and Latin. These are the lemmas that generate about 75% of the words found in a typical text. In Greek this means approximately 500 lemmas, in Latin, about 1000.The core lists were created using data provided by the Thesaurus Lingaue Graecae and the Laboratoire d’Analyse Statistique des Langues Anciennes (LASLA). 
  • All words not in the core lists are fully and accurately defined in running vocabulary lists that accompany each section of text. These lists are created using accurately parsed texts (mostly from LASLA), and English definitions appropriate to the author, typically based on print lexica specific to each author, such as the Vergilian dictionary of Frieze. Custom vocabulary lists based on user-selected criteria can be obtained at our partner site The Bridge, created by Bret Mulligan at Haverford College. 
  • Notes provide links to the geographic database Pleiades, to the Latin grammar of Allen and Greenough, the Greek grammar of Thomas Dwight Goodell, and to other authoritative reference works.


A pilot commentary on excerpts from Julius Caesar’s Gallic War, using notes selected from older school editions, was created in 2010 by Chris Francese and a team of Dickinson students on an earlier site using Mediawiki, in response to changes in the Latin Advanced Placement Exam. In 2011-2012 Francese created core vocabulary lists with the help of Wilfred Major, Marc Mastrangelo, and Eric Casey (Greek) and  Meghan Reedy (Latin), and a group of Dickinson students. A second pilot commentary, on Sulpicius Severus’ Life of St. Martin, with original notes by Francese, also began in Mediawiki. In 2011-2012 both pilot commentaries were transferred to the present Drupal site. Shortly thereafter new commentaries were added by Bret Mulligan, William Turpin, and Susan Stephens. The agreement with Open Book Publishers brought substantial new content in 2015, and more commentaries are in development. DCC has grown to become the hub of an international community of scholars and students working through the problems and opportunities of multimedia annotation. It now has a sister site for commentaries in Chinese, Dickinson Classics Online.

Philosophy and Approach

Digital annotation of classical texts has many potential advantages. In theory, it could provide easy access to all comments written on a specific passage (the so-called “digital variorum,” Heslin 2016). It could also provide a new freedom from space restrictions imposed by the print medium (“infinitely large margins,” Fowler 1999), and multiple-audience commentaries, with the ability of users to choose the level of notes they want. Digital annotation could also open up authorship through wikis and user comment features (Carlisle et al. 2016), and allow for machine-generated comments that would parse word forms and disambiguate geographical and proper names based on automatic language processing tools or voting features (Crane 2009).

In practice, however, various problematic issues—partly technical and partly related to scholarly culture—have emerged: a machine-readable form of citation that would enable aggregation of comments on a single passage is still under development (Rebillard 2009, Blackwell and Smith 2013). A usable TEI syntax for linked annotations is not yet available (Schmidt 2014). Design issues make it difficult to include all relevant information on limited screen space, and the dividing lines between different “levels” or audiences of classical commentary are not as clear cut as initially thought (Anderson 2016). “Open” commentaries on classic works have not been productive so far, and readers of such texts typically value scholarly expertise and are reticent about adding their own notes. Automatic parsing tools are not yet up to the standard of quality demanded by classical scholars (Francese 2012). Finally, the publishers that identify authors, ensure quality and consistency, and carry out peer-review for print commentaries do not yet exist for digital work.  In this turbulent context there are no routines, no standard accepted formats, and little likelihood of pleasing all audiences. 

DCC focuses on the needs of Latin and Greek learners and non-professional students. It prioritizes accurate scholarship, pedagogical utility, and attractive design, while remaining mindful of issues of infrastructure and networked data. It avoids the pitfalls of providing too much information, and of relying on open or wiki annotation, which would deprive the reader of the comfort of expert guidance. Our emphasis is on the humanistic learning and intellectual skills to be cultivated by reading the classical texts: precise appreciation of poetic language, close reading, cultural literacy, and skill in translation.
