How to organize too fiction books?
Organize them based on the publication date. Start with the oldest books at one end and the newest at the other. This can be interesting as it gives you a sense of the evolution of fiction over time. You can see how writing styles and themes have changed from the older fiction books to the more recent ones.
Categorize them by genre. Put all the romance fiction books together, mystery ones in another section, and so on. This way, when you're in the mood for a particular type of story, you can quickly go to that section. For instance, if you feel like reading a science - fiction book, you know exactly where to look among your 'too fiction books'.
You can organize them alphabetically by the author's last name. It's a simple and straightforward method that makes it easy to find a specific book when you need it.
