Scholarly journal Archivum Lithuanicum has a well established position and reputation among the Lithuanistic journals in Lithuania and in the world. It mostly publishes articles on external history of Lithuanian (i.e. cultural, social history of language), on Lithuanian manuscripts and printed texts, and on their textual criticism. Therefore this periodical is unique. It is being prepared by few scholarly institutions (4 universities and 2 research institutes). Archivum Lithuanicum is large in scope, since it is issued once a year in a single volume instead of traditional separate issues. Archivum Lithuanicum is the major journal for the history of external Lithuanian linguistic thought, and it continues shaping concrete research trends in the field. Archivum Lithuanicum was successfully published for over 20 years by now (vol. 1–24, 1999–2022).
