Source® Sans 3 and Source® Serif 4 are open source typefaces available on Google Fonts.
Licensed versions of Source® Sans Pro & Source® Serif Pro may also be used in place of the open source versions.
SPECIAL CONSIDERATION: when downloading files from Google Fonts, be sure to install the “static” fonts (e.g. Light, Regular, Bold, etc.) rather than the “variable” fonts as these are not fully supported by all applications. Discretionary and sparing use of all font weights and style variations are permitted.
