This is truly a question of a personal nature.

It may seem unrelated to the job, but the good news is you can make it relate to the job. When conducting your job search, it is important to keep up with your industry. What publications should you be reading as a career-driven person of your industry? Are there manuals, magazines, books, online sites, and blogs? If you're prepared, you have the perfect opportunity to show you've been keeping your skills and industry-knowledge up-to-date. This is also a great way to save yourself if you aren't a pleasure reader. If you do enjoy reading, you should discuss these books, as long as they seem appropriate. Discussing titles that show your appreciation of literature (even popular fiction) or your desire to learn (non-fiction) are fine.
