As of now, McGill Library provides access to three Making of the Modern Law databases:

The Making of Modern Law: Legal Treatises 1800-1926 
The Making of Modern Law: Legal Treatises 1800-1926 provides digital images on every page of 22,000 legal treatises on US and British law published from 1800 through 1926. Full-text searching on more than 10 million pages provides researchers access to critical legal history in ways not previously possible.

The Making of Modern Law: Primary Sources 
We use the term primary sources not in the historian’s sense of a manuscript, letter, or diary, but rather in the legal sense of a case, statute, or regulation. Designed to complement The Making of Modern Law: Legal Treatises, this archive offers online access to state and municipal codes, documents relating to constitutional conventions, and other resources in American legal history.

The Making of Modern Law: Trials 1600-1926 
Based on holdings of the law libraries of Harvard and Yale, and the Library of the Bar of the City of New York, the product offers online access to these important collections.

You can access the databases by clicking on Legislation and cases- foreign jurisdictions
