I am creating a database of book summaries. I visualise access to the database through the web browser as follows:

On the main page there are four subject categories to pick from. When the user clicks on a category they are taken to a page of titles of all summaries available in that category. When they click on a title they are taken to that individual summary.

My question is how do I trun the retieved plain text into hyperlinks that point to the individual summary.
