The resources described in the following table include both bilateral and multilateral treaty texts. If you have a citation to one of these sources, you can use it to retrieve the full text of the treaty. If you don't have a citation, you may still be able to retrieve the treaty text from one of these sources by checking the indexes (for the print versions) or by using the search tools (for the online versions).
Note that some of these sources are still being published and continue to incorporate newly concluded bilateral treaties. Others have ceased publication and include only older treaties within a specified date range. Some sources are more selective in their coverage of bilateral treaties than others, but no source is fully comprehensive.
