Hello,
If the book links are not opening and only the text is showing, it means the links are not clickable. This usually happens when the website has not added an active hyperlink or your browser is not loading it properly. Try opening the page in another browser, refresh the page, or long-press the text if you are using a phone to see if any option appears. If the link is not actually active, you will not be able to open it by tapping. In that case, check if the website has provided the books in another section like downloads, resources, or PDF list. If nothing works, it means the website has not uploaded the actual book file.
Hope this helps you.
