Expert writing Tips
Best practice
Use "which are in" to add non-essential, descriptive information about a noun. Remember to set off the clause with commas.
Common error
Avoid using "that" in place of "which" when introducing a non-restrictive clause (a clause that adds extra information but isn't essential to the sentence's meaning). For example, write 'The books, which are in the library, are available for loan' not 'The books that are in the library are available for loan'.
