No, that is not true. But it is understandable that you would think that. IAs statement seems written to obscure exactly what they did.

Read this: http://blog.archive.org/national-emergency-library/

> The National Emergency Library launched on March 24, 2020, and closed on June 16, 2020.

> After June 16, books in the National Emergency Library are available to one borrower at a time using controlled digital lending.

This very strongly implies that between March 24 and June 16, they did not pracise controlled digital lending by lending each copy only once at a time.
