Create categories for the various kinds of materials. List contents for category in (author) alphabetical order. Add place of publication and name of publisher for books and similar works.
Create as many categories as are required (in alphabetical order), and do not use all-inclusive categories. Common categories include: Books; chapters in books; articles; cases (with different jurisdictions in alphabetical order); legislation (with different countries in alphabetical order); treaties and conventions; internet sources; newspaper articles.
