To that end, the Horror Review Index page is where you should go to find horror titles to suggest to your library patrons. I will make sure always to update the page name with the date of the last added reviews.
I will also start having posts like this one where I will simply list the newest reviews. We are hitting the busy season, so I have a bunch of suggestions.
Finally, remember, your horror fans are not monsters, they just like to read about them.
