The first thing I did was changed the reviews into reviews, add the book and linked the reviews to the book. Open Library knows about two versions of the book. I linked both versions to the same author and linked the 2001 version to Wikidata. Finally I added the chapter in a haphazard way to the paper I am working on.
It is unlikely that I will ever read the book and it is very likely that others will frown on the way I added the book to Wikidata. However, for me "level 0 of data quality" applies; with data available particularly linked data, it is much easier to find fault and improve on what is there. I know that a bot will format the ISBN-10 entry I included.
The one reason why I add books is because books linked to OpenLibrary may be read by a wider public. Obviously not all books are available at this time, but the cumulative effect of adding all the books, all these links enrich the ability to read, to share in the sum of available knowledge.
