Glossary of fonts terminology, typographic terms, typefaces | design : talkboard
The invisible line where letters sit.
Typedia: Learn: Anatomy of a Typeface
A horizontal guideline indicating where the bottoms of characters without descenders appear to align. Often referred to in an imaginary sense. When more than one typeface is set, all characters usually appear to have the same baseline.
Font Glossary -
A line on which letters are said to sit; usual for Latin, Greek, and Cyrillic, but optional for other scripts; e.g., Hebrew or Devanagari, which instead hang from a headline.
Type Directors Club : Views : Type Dictionary
The imaginary line upon which text rests. Descenders extend below the baseline. Also known as the "reading line." The line along which the bases of all capital letters (and most lowercase letters) are positioned.
Typography Terms - Proxima software
The imaginary line on which the letters of a font sit.
ParaType help & info - Font Terminology Glossary
The line on which letterforms rest. (Round letters like "e" and "o" normally dent it, pointed letters like "v" and "w" normally pierce it, and letters with foot serifs like "h" and "l" usually rest precisely upon it.)
In typography, an invisible horizontal line on which the feet of all the characters on a line of type is set, used for proper alignment of type. See Alignment. Also known as a z-line.
PrintWiki - the Free Encyclopedia of Print
The virtual line on which the text characters are set, not including the ascenders and descenders of the characters.
Glossary of Printing Terms -
In typography, the baseline is the imaginary line upon which a line of text rests. In most typefaces, the descenders on characters such as g or p extend down below the baseline while curved letters such as c or o extend ever-so-slightly below the baseline. The baseline is the point from which other elements of type are measured including x-height and leading. The baseline is also significant in the alignment of drop caps and other page elements.

Harris, David. The Art Of Calligraphy. Dorling Kindersley Publishing, 2005, 128p. (p.122)
Whether written by hand or set into type, the Latin lowercase alphabet implies an invisible staff consisting of at least four lines: topline, midline, baseline and beardline. The topline is the line reached by ascenders in letters like b, d, h, k, l. The midline marks the top of letters like a, c, e, m, x, and the top of the torso of letters like b, d, h. The baseline is the line on which all these letters rest. The beardline is the line reached by descenders in letters like p and q. The cap line, marking the top of uppercase letters like H, does not necessarily coincide with the topline of the lower case.
Round letters like e and o normally dent the baseline. Pointed letters like v and w normally pierce it, while the foot serifs of letters like h and m usually rest precisely upon it.
