fnt­guide – Doc­men­ta­tion of LaTeX font com­mands

Doc­u­men­ta­tion of com­mands for se­lect­ing fonts, as well as those for defin­ing the data-struc­tures used by the se­lec­tion com­mands.
For fur­ther guid­ance, two pa­pers may be help­ful — “Essen­tial NFSS” by Se­bas­tian Rahtz, writ­ten shortly af­ter the ap­pear­ance of LaTeX2ε, and “Font se­lec­tion in LaTeX” by Wal­ter Sch­midt.
Fnt­guide is part of a set of doc­u­men­ta­tion that also cov­ers new LaTeX 2e com­mands, class and pack­age writ­ing, type­set­ting Cyril­lic, LaTeX font en­cod­ings, con­fig­u­ra­tion op­tions and mod­i­fi­ca­tion of la­tex.
