I would also ask these people to optionally write or improve a summary of the book in Wikipedia if it has an Wikipedia article (or should have one). In many cases, it’s not only EAs who would do more good if they knew ideas in a given book, especially when it’s on a subject like pandemics or global warming rather than topics relevant to non-altruistic work too like management or productivity. When you google a book, Wikipedia is often the first result and so these articles receive a quite lot of traffic (you can see here how much traffic a given article receives).
