Where can I find them?
If you are using XeTeX / XeLaTeX take a look at the "Unifraktur" project at http://unifraktur.sourceforge.net Although the site is written in German language you might be able to find the "download" section.
They offer only 2 blackletter fonts, "UnifrakturMaguntia" and "UnifrakturCook", but these work perfectly with XeTeX. (These are Unicode fonts, i.e. the "long s" (ſ) is positioned at its official Unicode position. Nothing more is needed for typing a text, especially all ligatures (which are quite essential in blackletter fonts) are automatically set by XeTeX, as long as you don't manually prevent this [wherever necessary] by the usual "no ligature" macro.)
If you don't mind installing your own fonts (see, for example, Displaying medieval scriptures and neumes in TeX), one of the greatest sources I've found is at
You will find many, many varieties of fonts there, including fraktura, rotunda, textura, Schwabacher, and other more modern forms.
Other, lesser sources include:
and for non-blackletter
