This one’s hard to explain, so pay attention.
Access as Verb
When used as a verb, “access” is not followed by “to.” Just write:
- “Thanks to the Internet, I can access information at any time.”
- “Students can access a lot of books at the campus library.”
- “Everyone wants to access the Internet nowadays.”
This is the most common use of the word, I think.
Access as a Noun
When used as a noun, “access” can be followed by “to.” As in:
- “Thanks to the Internet, students have access to a lot of information.”
- “Students who visit the library have access to a lot of books.”
- “Students want access to more books.”
Don’t write:
- “On the Internet, students can access to a lot of information at any time.”
