A font catalog or font catalogue, also called a type specimen book,[1] is a collection of specimen of typefaces offering sample use of the fonts for the included typefaces, originally in the form of a printed book.[2] The definition has also been applied to websites[3] offering a specimen collection similar to what a printed catalog provides.
In printed form, they were typically created for type foundries and others who sold type to show what typefaces were available for sale to printers. Printers also made font catalogs to demonstrate the fonts they had on hand for printing projects.[1] In all forms, font catalogs aid typesetters and graphic designers in choosing appropriate typefaces or narrowing down candidates for the typesetting or design process.
