Hey there, @krisp303! Thanks for contacting us. I’m happy to help you.
As mentioned, it is not possible to add HTML to the product title.
If you are selling books, you might want to look for plugins that can help you with that. Some plugins can have several features created specifically for book products.
You can search on the Plugins > Add New section of your dashboard or on a search engine like Google, for example.
Please note that we do not provide support for third-party plugins, so it is good to check the plugin thoroughly to see if it is reliable. You can find more about this in this guide.
If you want to add the Author by using custom code, while we can’t provide support for code customization as per our support policy, we do our best to offer advice and direct you to appropriate resources.
You can visit the WooCommerce Facebook group or the #developers
channel of the WooCommerce Community Slack. We’re lucky to have a great community of open-source developers for WooCommerce, and many of our developers hang out there too.
Please let us know if there’s anything else we can do to help or if you have any questions.
Have a wonderful day!
