Perhaps you should try some spelling variations:
"autodidactism" » "autodidacticism", "autodidactus", "autodidacts"
"autodidaktism" » "autodidaktisch", "autodidaktin", "autodidaktische"
"autodidactic" » "autodidaktisch", "autodidakten", "autodidakt"

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: (("autodidactism" OR "autodidaktism") OR "autodidactic").
• Removing quotes may allow a broader search: (( autodidactism or autodidaktism ) or autodidactic ).
• Adding a wildcard symbol may retrieve word variants: (("autodidactism" or "autodidaktism") or "autodidactic")*.
