The Law Library holds legislation from the middle ages to the present day. The oldest piece of legislation still in force is the Statute of Marlborough enacted in 1267. You can see it in paper copy in the library or online anywhere in the world at any time accessing out online databases. As well as current versions of legislation you can also see repealed historical versions of laws which might be vital for your study and research. You will also be able to trace the progress of Bills as they progress through Parliament on their way to possibly becoming law.
In the databases listed alongside you can search for legislation by title, subject or keyword. Primary Legislation usually takes the form of a Public General Act passed by Parliament but Private Acts and Local and Personal Acts do also exist. (Various other Orders and Measures may be considered Primary Legislation). Secondary Legislation sometimes also called Delegated Legislation usually takes the form of Statutory Instruments and can come in the form of Orders, Rules or Regulations.
Here are some examples of Acts and Statutory Instruments (SI's) cited in the OSCOLA referencing style..
