# About the frequency corpora
The frequency corpora used to compute rarity/sophistication measures
can all freely be downloaded on-line; **we are not their owners**.
We have merely uploaded these files to OSF.io to ensure that all scripts
work out-of-the-box.
**Lexique 3** (`FrequencyCorpora/LEXIQUE_FR.csv`) can be downloaded from
