Hey,

I noticed that your csv merge files contain more than 100 millions lines (for the authors for example).
I do not understand why it could contain more than the actual number of authors in a single file ?
Moreover, I did not find the exact explanation in your documentation.
If you have any simple explanation, other than disambiguation, it could help me a lot !

Thanking you in advance for your answer.
