Including introduces a clause. Include/ included almost always need to have a subject before them in the sentence Examples -they gave us a list, which includes/included a few books - there was a list of things, including a few books - the book talked about many things, including friendship and adventure - the things that were discussed in the book include friendship and adventure Hopefully I explained it ok, it’s a difficult thing to explain. There’s no difference in meaning, the sentence just has to be formed differently
