This book, if uploaded to Wikibooks, will be able to come up with Google
searches.
However the book will NOT be able to be eternally protected from editing by
other authors.
The donating professor would, in practice, likely be the main or only
author/editor of the online text, but Wikibooks would NOT be able to host a
static text over the long haul.
For a limited time, as a service to an author or group of authors, Wikibooks
could offer edit protection. But that protection would eventually have to be
lifted.
Perhaps the professor would like to host a static version of her work on
another site, then offer the text to Wikibooks to create a "living",
community-editable version.
