I like to read several things: newspapers, magazines, books, and poetry.
Explanation:
I used bold font where I edited the sentence. When you use the colon(:), you are about to use a list. That is exactly what happens in this sentence, so you replace the semicolon(;) which is used to join two or more ideas.
Whenever you are at the end of a list, you always add a comma(,) at the end of the last item before "and," so I put a comma there.
