libertinus

Libertinus is an open-source typeface family that continues the lineage of Linux Libertine. It provides a set of serif and sans styles designed for versatility in both body text and display use, with a focus on high readability and broad character support. The family is commonly used in academic publishing and digital typography, particularly in TeX/LaTeX workflows, as an open alternative to proprietary fonts.

The design philosophy of Libertinus emphasizes classic, humanist-influenced letterforms with robust Latin alphabet coverage, along with extended support for Greek and Cyrillic scripts. It includes features expected in scholarly fonts, such as ligatures, small caps, old-style numerals, and comprehensive diacritic coverage, making it suitable for multilingual typesetting. A mathematical variant has also been provided, aligning with TeX-based workflows.

Libertinus originated as a community-driven open-source project to modernize and extend Linux Libertine with improved hinting, micro-typography, and more consistent metrics across weights. It is distributed under an open-source license, enabling wide adoption and modification by designers and institutions.

Availability: Libertinus is distributed through major font repositories and included in several Linux distributions and TeX/LaTeX ecosystems, where it serves as a flexible alternative to traditional serif and sans faces.
