Hey @JonJC -- thanks so much for this contribution, and apologies for the very delayed reply. Great idea for the books section, and I agree this should be on the list.

So all change need to be merged into the dev branch, so they can be reviewed before merging to main -- it looks like there are some conflicts with. you change now that I pointed it to the dev branch.

Would you be able to submit a new pull request pointing to the dev branch, or resolve these conflicts instead? I'm also happy to do this for you if you would like, but I also want to make sure your contribution is tracked in git!
