Hi Christopher,
I think it make sense to add that book to the mentioned page.
You should simply open a Jira issue [1] (use the "documentation"
component), put as much as details as you can in there and someone from the
committers will pick it up.
Regards,
Tommaso

Dear Solr users/developers,
I'm sending an email here because I wasn't sure where to ask.
My name is Chris and I work for Manning Publications in the marketing
department. We have a book that we are interested in listing on the
webpage: http://lucene.apache.org/solr/resources.html#solr-books
