1. Lack of portability: Physical books can be heavy and take up a lot of space, making them difficult to transport. This can be inconvenient for people who want to read while traveling or commuting.
2. Difficulty in finding specific information: Physical books can be cumbersome to search through when trying to find specific information. Readers may have to flip through dozens or even hundreds of pages to find the information they need, which can be time-consuming and frustrating.
