LaTeX uses them with the following packages: - amsfonts (A--Z, k) - mathbbol (complete alphabet with greek, uses bbold fonts) The german LaTeX FAQ tells, there'd be the fonts: - bbold (sans, complete, by Alain Jeffrey) - doublestroke (sans and serif, caps and "1, k, h", by Olaf Kummer) - bbm (several variants, by Gilles F. Robert) I remember an other free(?) blackboard font at http://www.yandy.com I found an reference to an article by Gerd Neugebauer in "Die TeXnische Komödie" 4/1996, 1/1997 about several possibilities. And there should be a file "blackboard.ps" at CTAN:doc/blackboard -- Grütze für alle! Hraban.
