DM Serif Text is a lower-contrast counterpart to the high-contrast DM Serif Display. While the serifs remain delicate, the DM Serif Text family is a more robust variant of the Display sibling, intended for smaller sub-headings and text sizes.
DM Serif Text supports a Latin Extended glyph set, enabling typesetting for English and other Western European languages. It was designed by Colophon Foundry (UK), that started from the Latin portion of Adobe Source Serif Pro, by Frank Grießhammer.
The GM Serif project was commissoned by Google from Colophon, an international and award-winning type foundry based in London (UK) and Los Angeles (US) who publish and distribute high-quality retail and custom typefaces for analog and digital media. To contribute, see github.com/googlefonts/dm-fonts
