Not really. ShowHN’s are for interactive things and are supposed to be free and generally shouldn’t require account creation.

“Reading material” is specifically called out as being off topic!

I was tempted with Show HN, but it also seems more like demos, and this is more a link to an open access book so I thought it was more reading material.
