I feel comfortable reading physical books (maybe, I'm an old school).

@@ulugbeknur I also read physics books, but I was asking about something else. for example, in Uzbekistan and Russia, books are published mainly with hard covers, and in America, as far as I know, they are published more with paperback (I hope I'm expressing myself correctly)

@@mushukxon In the US, I've mostly seen books in three different types of formats: audio books (books narrated either by an author or an actor), digital (e-books accessible in a pdf or kindle formats); paperback (= a thin paper cover) and hardcover (= a thick cover). Hardcover books are typically more expensive than the paperback formats. Because I usually check them out from the local or my university libraries, I don't pay much attention to the format.

In Uzbekistan, my major was Translation. In the US, I did my MA in TESOL and PhD in Applied Linguistics. Please, kindly visit my homepage to learn about my academic background: ulugbeknur.wixsite.com/profile You can find my CV too .

@@ulugbeknur I appreciate it, thanks
