To the casual observer, Gentium may seem similar to Times New Roman, with a stacked letter-press type lowercase, delicate serifs, and legibility at very small sizes. But Gentium has more rounded glyphs, and a much less harsh overall appearance. Gentium supports a wide range of Latin- and Cyrillic-based alphabets, and is available in a number of versions to fit all your business needs.
Gentium Basic includes upper and lowercase, numbers, punctuation, special characters, and a limited Latin character set. Gentium Book (designed by Gaultney with Annie Olsen) is a slightly heavier version. Both Gentium and Gentium Book include italic, bold, and bold italic faces. In addition, Gentium Plus offers extended Latin glyphs, archaic Greek symbols, and full extended Cyrillic script support; but currently includes only regular and italic faces. Gentium Alt includes more than 2400 kerning pairs and flatter diacritics designed to improve appearance when writing non-English (and offers fun options that may not be typographically correct, but add flair).
Gentium fonts are free for both personal and commercial use, in addition to being open source under the SIL Open Font License (which permits both redistribution and modification). Embedding is installable.
