When it comes to learning ( or studying) law, referring to the written law i.e. statutes is perhaps the most important thing. Regardless of whether you are in common law or civil law country, statutes provide students with the text of law that legislative authorities subject everything to. One of the most important rules of interpretation of law is that the text of statutes is what the law is. If the text is clear as to what it intends to put forth, the court of law should not bother to usher in new considerations as far as rule of law is sought to be enforced.  In other words, one should take into account only the way law has been written in order to understand what the law expects of society and its constitutents. However, if the text is ambiguous or the application of law assumes new dimensions in relation to evolving nature of society, the scholars and the courts should refer to other apsects in order to resolve an issue. Therefore, one might be inclined to understand the context of law reflected by its aims and objectives and debates engaged into by legislators while formulating the law in Parliament.

The second important material which law students should have access to in order to study law is case laws. It refers to the way courts have interpreted and applied law to cases before them. This helps students in understanding, analysing and, finally, knowing whether law has been applied the way it should have been or other extraneous considerations factored in while delivering judgement. Knowing what law is, through reading statutes, is one thing and seeing how the same law is applied to real sitautions at hand by the courts, through referring to case laws, is another. These two aspects of studying law complement each other and afford students an insight into how legal system or judiciary works. 

The third important material that law students should have access to, but only in the end, is law text books. It is pertinent to mention that law text books include not only references to important legal provisions of any statutes and how they have been interpreted by courts but they also are, primarily, a commentary on law and its application by eminent scholars. The very fact that different scholars have different takes on every law and its interpretation give some colour to text books and the students should, therefore, appraoch this material in the end. If the students refer to only law text books, they are likely to be conditioned by personal opinion of the authors who wrote the books. This scenario is not very optimal for development of jurisprudence and building law scholars who have independent and critical thinking. 

In view of the aforementioned, it can be concluded that in order to study law  both the statutes and the case laws form the most important materials followed by the law textbooks written by eminent authors who are almost institutions in the field of law.
