The source that you would find only in digital form is an e-book. E-books are electronic versions of traditional printed books that can be read on devices like e-readers, tablets, or smartphones. They are specifically designed for digital consumption and are not available in physical printed form. E-books offer convenience, portability, and accessibility as they can be easily downloaded, stored, and read on various digital devices.
Here's why the other options are not exclusively found in digital form:
1. Magazine: Magazines are available in both print and digital formats. While some magazines have shifted towards digital-only publications, many still offer printed copies.
2. Newspaper: Newspapers are also available in both print and digital formats. Although many newspapers now have online versions, printed newspapers are still commonly found.
3. Encyclopedia: Encyclopedias can be found in both print and digital formats. While printed encyclopedias were more prevalent in the past, digital encyclopedias like Wikipedia have become popular sources of information online.
In conclusion, e-books are the only source listed that is exclusively found in digital form, making them a unique digital resource for reading and learning.
