text: •**Charging for use to support sustainability of the training corpus itself:**While wanting 
  to ensure broad access to this resource, it is important to consider economic 
  sustainability, including support for continuing to update the resource with new works 
  and appropriate tooling for AI training. Requiring some form of payment to use the 
  resource could support sustainability, perhaps with different requirements for 
  different types of users (e.g., differentiating between non-commercial and 
  commercial users, or high-volume, well-resourced users and others).   40 
  
  •**Ensuring beneﬁts of AI are broadly shared, including with book authors or**
  **publishers:**The creation of a training resource might 
  lower barriers to the 
  development of AI tools, and in that way support broadly shared beneﬁts by 
  facilitating greater competition and mitigating concentration of power. On the other 
  hand, just as concentration of technology industries is already a signiﬁcant challenge, 
  AI might not look much different, and the beneﬁts of this resource may still simply go 
  to a few large ﬁrms in “winner takes all-or-most” markets. The workshops discussed 
  how, for instance, large commercial users might be expected to contribute to a fund 
  that supported contributors of training data, or more generally to fund writers, to 
  ensure everyone contributing to the development of AI beneﬁts.
