FONTES provides annotated full-text versions and image documents on early modern discussions of art and artifacts in the broadest sense. This includes not only all text genres that Julius von Schlosser included in his standard work "Die Kunstliteratur" (1924), but also, for example, antiquarian literature, archival sources, poems, commentaries, passages from lexical and encyclopedic works. Particular emphasis is also placed - especially since the relaunch of FONTES (and thus a change of subtitle) in 2022 and from No. 93 onwards - on the importance of pictorial documents, i.e. publications consisting largely or entirely of pictorial plates on collections, patterns, art instruction, reception of antiquities, and the like.
