An employee has the right to answer in writing any such materials in a personnel
file on July 1, 1983, as well as any such materials
filed thereafter, and the answer shall be attached to the
file copy.
It also makes it so that if you have a change to your book's cover or interior, you don't have to recycle a bunch of already printed
copies you can no longer sell; you can simply update your
file and every
copy sold and printed
thereafter will reflect the change.
