That link is dicey. I'm not sure why, but it doesn't always land in the correct page. It usually ends up in a disambiguation page.

Goodreads is commercial, but it does a good job of describing books and series of books.

[UPDATE] Ah. Figured it out. It's the trailing period. I think HN removes it from the link.

I've fixed it now. From https://news.ycombinator.com/formatdoc:

If your url gets linked incorrectly, put it in <angle brackets> and it should work.

Thanks so much!

I've read that very passage in the Ts&Cs, numerous times, and it didn't sink in.

It will, now...
