Bcom Pass SOL - Law only one book and no book for BST?

I am in SOL and doing BCom Pass 1st Year.

 I received one book for LAw and no book for business studies.

Can someone tell me if there is just one book for law or are there two books? I am asking become udner syllabus there are acts given for industrial law as well, but in this book there are no chapters from industrial law.
