ABOUT

bbold [Alan Jeffrey]

bbold is a blackboard bold math symbol font written in metafont by Alan Jeffrey in 1994, and later converted into a type 1 font. This CTAN page can be used for downloads. Type 1 versions are here, courtesy of Berthold K. P. Horn and Khaled Hosny (2007-2010).

Done for Y&Y, the weight of the original bbold font was a good match to Computer Modern, with upper and lower case Latin and Greek letters as well as punctuation and a number of symbols. The font was the property of Y&Y, and, after their dissolution, the copyright was gifted to TUG in 2007. Michael Sharpe's package bboldx (2021) extends the original by adding a couple of glyphs and adding two new weights. Where the original stem widths were 40 units, the additions have stem widths of 56 units and 90 units respectively.
