In addition to his work as a teacher and administrator, he published widely on medieval French literature.
This dissertation built a corpus of Old French lyric poetry that Van den Boogaard then put into a computer database.
In 1970, he enlarged the database and generated statistical information about several genres of medieval French literature.
A bibliography of his publications, listing two dozen articles as well as book reviews and collaborative papers, is included in the introduction to Autour de 1300, pages xxi-xxiv.
Van den Boogaard's style of academic writing was modern, modest, interdisciplinary, good-humored, and accessible to a broad audience.
