Designed by Robert Schenk, OpenBook is a novelty font published by Ingrimayne Type.
OpenBook is a novelty font that has letters on pages of a book. It is caps only and monospaced. The letters on the upper-case keys are on the left-handed pages of an open book and the letters on the lower-case keys are the same letters but on the right-handed pages of an open book. One could alternate upper and lower case keys to get letters on complete books, but the Opentype feature of contextual alternatives (calt) does this automatically. Several previous typefaces from IngrimayneType used the calt feature to alternate shapes that fit together in an interlocking pattern, such as alternating concave and convex shapes. OpenBook uses the calt feature in a different way, to alternate two halves of a symmetrical shape.
To provide two copies of numbers and common symbols, some non-alphabetical characters are unavailable because their slots were taken by the second form of the number or common symbol. If stylistic set one (ss01) is turned on, spaces are replaced with empty pages. This may leave you with unwanted spaces at the end of lines, and to eliminate them, turn off the feature (or change the font) for these spaces. The empty pages can be used in a layer to add color to the text. There is also a second set of empty pages with a filled page that can also be used in layers. (See poster for examples.) These pages are on the (logicalnot multiply) and (register divide) characters for the first set and on the (ordmasculine ellipsis) and (macron trademark) keys for the second set. Finally, OpenBook has a large set of accented characters if anyone should need them.
The letters used on the books were derived from the font Myhota-Bold. OpenBook has limited uses and is priced accordingly.
