[6] The second edition ("AGLC2") in 2002 expanded its rules to include more sources: transcripts (court, television, and radio), explanatory memoranda to legislation, translations, parliamentary committee and royal commissions reports, the constitutional convention debates, speeches, and letters.

It expanded its coverage of basic international sources: decisions of the European Court of Justice, the WTO, and GATT.

The international legal materials (Part IV) were greatly expanded and the foreign jurisdictions (Part V) covered now include China, Hong Kong, France, Germany, Malaysia, Singapore, and South Africa.

Some rules were changed: for example, citations of books now require publisher information.
