This is the initial sentence of the Standard Course Book of HSK5, chapter 20. Please help me make the literal translation of it.
小人书(comic)，是(is)一种(a kind of)以(?)书(book)的形式(form)出版(to publish)的连环画(lianhuanhua)。
What kind of book is the 以书? I know that 以 means by or with but how does it make sense here?
小人书 means comics or any "young people book"? What is the difference between the 小人书 and 连环画? Maybe the former is the western comic and the latter the Chinese comic?
How to make the sentence make sense?
