Lias, Journal of Early Modern Intellectual Culture and its Sources (Dutch for sheaf or file; French: liasse) is a biannual double-blind peer-reviewed academic journal covering the history of learning and education in a very broad sense.

The journal was established in 1974 by a group of Dutch and Belgian scholars, and subtitled Sources and Documents relating to the Early Modern History of Ideas.

The aim was to provide a platform for the edition and study of primary sources of relatively small size pertaining to the cultural and intellectual history of Early Modern Europe.

[2] The majority of the articles in the first 36 issues concentrated on texts from, or relating to, the Low Countries.

The journal also accepts studies based on neglected printed sources.
