Perhaps you should try some spelling variations:
"autodidacta" » "autodidactus", "autodidakt", "autodidakten"
"autodidactic" » "autodidaktisch", "autodidakten", "autodidakt"
"autodidactics" » "autodidaktischs", "autodidaktens", "autodidakts", "autodidacticism", "autodidactus", "autodidacts"

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