Vera consists of serif, sans-serif, and monospace fonts. The Bitstream Vera Sans Mono typeface in particular is suitable for technical work, as it clearly distinguishes "l" (lowercase L) from "1" (one) and "I" (uppercase i), and "0" (zero) from "O" (uppercase o), in similar fashion as Verdana and Tahoma fonts.
Bitstream Vera Sans is also the default font used by the Python library Matplotlib to produce plots.[2]
Bitstream Vera was released in 2003 with generous licensing terms and minimal restrictions that are nearly identical to those found in the Open Font License, which was not formalized until two years later. The main restrictions were a prohibition on reselling the fonts as a standalone product (though selling as part of a software package is acceptable), and that any derivative fonts not be distributed under the name "Vera" or use the Bitstream trademark.
The DejaVu fonts are a prominent expansion of the Bitstream Vera fonts.
