If you conduct a Google search to retrieve a copy of a law or case, make sure to evaluate the website's authoritativeness and reputability. Laws and cases from Sri Lanka are not available on Westlaw or Lexis. 

Older laws and cases may be found in print. If you are looking for older legal materials, see the Sri Lanka research guides linked above for lists of law reports that you can search for on NUsearch by publication name. 

In addition to checking country-specific databases and websites to find the foreign legal materials you need, subject-specific collections of laws, which collect laws from various countries pertaining to a particular subject, can be useful resources to incorporate into your research process. These resources often have better search capabilities than foreign government websites. For additional suggestions for subject law collections beyond the selected databases listed below, see the GlobaLex Foreign Law - Subject Law Collections on the Web research guide.
