Since Rotary a global organization, and two of their areas of focus around around clean water and eradicating polio, maybe point them to projects that would help them towards those goals. For example, finding local partners to help them with translation of articles and enrichment of key articles might be a terrific starting point. Also, translation of their own article (or at least having better representation of their work in key languages) might also assist them with their goals.

When I go back to edit the resulting citation it seems to have saved it as
a text block and not as a book citation with the various fields?

Hi, this seems to be working differently than when launched. For example the ISBN 9788611177434 which is used in the WMF blog post https://blog.wikimedia.org/2017/05/11/wikimedia-oclc-partnership/ no longer works and in fact throws up an error. Have you worked with Karen Combs at OCLC? If not I can put you in touch.
