You can purchase books as per syllabus if you are starting your law college and purchase few journals like AIR,SCC,Cr. L J. Judgement Today and Jr. of BCI. Later on you can purchase books release recently so that u can have a sound collection. Also try to write existing law universities and colleges for registering your law school in the list for sending law journals and newsletters etc.
If needed my help in this regard please do tell me.
