State most commonly used subsidiary books.
Subsidiary Books are the books that record the transactions which are similar in nature in an orderly manner. They are also known as special journals or Daybooks. In big business institutions, it is not easy to record all the transactions in one journal and post them into various accounts. So, for the easy and accurate recording of all the transactions, the journal is subdivided into many subsidiary books. For every type of transaction, there is a separate book.
