Essays and articles in the following directories should be translated in all available languages:
In these important directories, however, there are articles of historical or peripheral interest only, for which new translations are not necessary. For instance, /philosophy/sco/*, /philosophy/*-old.html, /licenses/*_seminar.html, /philosophy/economics_frank/frank.html, etc. Please use your judgment. (The existing translations of these articles should be maintained, though.)
The /proprietary directory is important, but it changes as fast as a newsfeed. Don’t start translating it unless you intend to update the translated pages over the long term.
