Librum Sans is a 4-font family specifically built for its use in book style. Its vertical metrics are identical to Librum, Bream, and Librum E. So, it works well for confrontation heads, embedded styles, and so forth. The character sets and OpenType features are identical to Librum and Bream.
The font styles were developed as a 15-font book design group whilewriting my new book, Practical Font style Design With FontLab 5.
