Perhaps you should try some spelling variations:
"autodidactic" » "autodidaktisch", "autodidakten", "autodidakt"
"autodidacticism" » "autodidaktischism", "autodidaktenism", "autodidaktism"
"autodidacta" » "autodidactus", "autodidakt", "autodidakten"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ("autodidactic" OR ("autodidacta" OR "autodidacticism")).
• Removing quotes may allow a broader search: ( autodidactic or ( autodidacta or autodidacticism )).
• Adding a wildcard symbol may retrieve word variants: ("autodidactic" or ("autodidacta" or "autodidacticism"))*.
