At the bottom of each book review, I put a few lines of information about the book itself. The title line includes a non-affiliate link to smile.amazon.com (the front-end where affiliate money instead goes to the charity of your choice). I put the publisher's genre (or my best guess if I can't find one), then the publisher's line has a link to the publisher's page for that book (if I can find one). After that is release date and the type of book and number of pages.
Book reviews are tagged as book-reviews or book-notes (because they are less than full reviews in my eyes). Additionally, I'll add any/all that I think apply. The indents are cumulative. I'll never have a business review that isn't also tagged as nonfiction.
