Important multilateral treaties will often have their own websites. Here, Google is your friend. Try searching for your treaty by name. For example, a search for the Basel Convention returns several useful and relevant pages.
If you are working with an important treaty, one of the fastest ways to find the authentic text and status of participating countries is via the
UNTC Advanced Search
UNTC Title Search
Sometimes, especially if your treaty is obscure or you are looking in the footnotes of an article, you may have a UNTS (or LNTS) citation but not the name of the treaty. In such cases, HeinOnline's United Nations Law Collection is the place to go.
At the top of the page, underneath the content of the library is a "Finding Aids" section. Here, enter the UNTS or LNTS citation. This search takes you to a specific page in the UNTS volume so that you can identify the name of the treaty, important dates, and signatories at time of publication. Remember to update this information before using it!
If you don't have a title or citation for your treaty, you will have to look it up by subject matter. For example, you know that there is an international agreement regarding the transportation of hazardous waste between countries but you don't know what it is called.
Electronic Information System for International Law (EISIL)
Multilateral Treaties Deposited with the Secretary General (MTDSG)
The MTDSG Status of Treaties is organized into 29 subject categories.
Each of these categories is further subdivided by subtopic. For example, Chapter 27 (XXVII) on the Environment is further subdivided into 16 environmental topics.
Topic 3 covers hazardous waste and includes:

Treaty?
What is and isn't a treaty can be a very complicated issue of international and domestic law and is outside the scope of this research guide. For ease of use, all international agreements, conventions, understandings, and treaties that may be included in the various resources described in this guide are referred to simply as 'treaties'. Please keep in mind that not all the documents contained in the resources described may carry the full weight of a 'treaty' as defined by international law. These various types of agreements do often have very similar documentation. That documentation is the focus of this guide.
Treaty Documentation
The type of treaty material you are looking for will vary with the type of research. Most commonly, you will want to find:
Where to Look?
In addition to sponsoring the creation of treaties, the United Nations also serves as a central repository and notification center for treaties created outside the auspices of the UN. A researcher will often have to look in a few places to find all the treaty information she needs. This guide provides instructions for finding treaties using:
A treaty can appear in the UNTS via a few different pathways. The chart belows provides a visual summary of when you can expect a treaty to be in the UNTS and if it is not there, where else you might look.

- from the Title Search Tab, type in the exact title (select match phrase) or a few key words (select match all these words)
- NOTE: this search returns the main treaty document AND subsequent and related documents.
- NOTE: the title search is not always effective, especially for older treaty documents that may be lacking good metadata.
Whether you are searching through the UNTS or browsing the MTDSG, the treaty record is the same and contains valuable information for the researcher. The UN Office of Legal Affairs has a webpage explaining the information found in the treaty record.
Once you have conducted your search, you will see a brief list of treaties. You can re-order your list by clicking on one of the other headings.
The Registration Number is assigned to the treaty by the Treaty Section of the Secretariat when a member state submits a treaty for registration. Registation is required before a treaty can be invoked before the ICJ or any other organ of the UN. Registration numbers beginning with the letter "I" refer to treaty 'instruments' and numbers beginning with the letter "A" refer to treaty 'annexes'. Important information is often included in the annexes, so these documents should not be overlooked in your research.
Click on the relevant title to go to the Treaty Record.
The treaty record is the same whether you go through the MTDSG or the UNTS. At the top of the record, you see some basic information. The "STATUS AS AT" information displays the current time (e.g. the time you ran the search) and does not mean that treaty gnomes are updating status information for treaties 24-7. Generally, information is updated within the month. Next comes the chapter information for the MTDSG, the official title of the treaty, and the place and date on whic it was concluded.
The entry into force date comes next. This date is negotiated as part of the treaty and so reference is made to the appropriate article. Note the registration date is the same as the entry into force date. This is because a treaty cannot be registered with with the Secretary General until it has entered into force. The Status information provides a summary of the number of Signatories (those supportive of the idea) and Parties (those legally bound).
The next section, entitled "Text" is important. It is akin to the legislative history of a domestic law. It begins with the initial publication (and translated copies) of the treaty in the UNTS with volume and page number (what you need to construct a BlueBook citation!). Next, listed in chronological order, are all the subsequent depository notifications (C.N.) made by the parties ammending the text and associated annexes of the treaty.
Individual Country Ratification Information
Beneath the identifying information and treaty amendments comes the status information for participating individual countries. This information is important for understanding a country's legal obligation under the treaty. While this information is updated, there is some lag. If you suspect a country's status has changed, check with another authoritative source such as that country's state department or office of foreign affairs. In the example above, Afghanistan was a signatory to the treaty (likely participating in the treaty negotiation) but never ratified the treaty through their domestic process. Albania was not a signatory to the treaty but did acede to if after it entered into force.
Algeria aceded to the treaty after it entered into force, but it did so with a RUD (Reservation, Understanding, or Declaration). A RUD is a unilateral statement by the country, made when joining the treaty, which purports to modify or exclude the legal effects of some portion of the treaty. Some treaties prohibit RUDs. In the example of Algeria aceding to the Basel Convention, Algeria included a declaration stating that both parties must agree to submit a dispute to the ICJ or an arbitral body before that body has any jurisdiction. The RUD is hyperlinked from Algeria's name in the status table and all the Declarations are listed in a table immediately following the status information.
Argentina has dates in both columns, meaning it was both a signatory and went through the domestic process of ratification. A detailed explanation of the status information is available in the UN Treaty Handbook.

The MTDSG allows for an Advanced Search, an Index Search, a full text search, and a search by participant.
While the Advanced Search screens in the UNTS and MTDSG are similarly structured, the quality of the search results in the MTDSG are much higher. One suspects this is due to the smaller number of treaties contained in the MTDSG.

Full Text Search
The Full-text Search does search through the PDF treaty documents. You can search for single words or for exact phrases. The resulting list shows you both the UN and LON multilateral treaties containing your word, but not where it appears or how frequently. Once the PDF of the treaty is opened, you must conduct the search in your PDF reader again to locate the word or phrase.
The default page when you enter the MTDSG contains the UN treaties by topic.
To the left is a tab containing excellent introductory information: an explanation of the scope of the MTDSG and summary of the types of status a country may have in relation to a treaty.
Immediately to the right, are the League of Nation (LON) treaties. Historical Information covers sovereignty and territorial changes for countries. The INDEX is organized by MTDSG Reference number and can also be searched. The search options are discussed below.
When looking at the default page, UN treaties by topic, you can see that the treaties have been organized into 29 chapters by topic. If we want to find the Basel Convention on the Control of Transboundary Movements of Hazardous Wastes and their Disposal, we would first browse through the list of topics.
Transport & Communication and Environment both seem like potential Chapters where the Basel Convention might be listed, since it is about the movement of hazardous waste.
Most likely, if you have the name of a specific convention, you will just search for it. However, if you know that there is a treaty dealing with hazardous waste, but don't have an exact name, then browsing is a good option. This treaty is more about the topic of hazardous waste than it is about transportation, so select the hyperlinked chapter 27 for Environment treaties.
Once you locate the Basel Convention (listed as the 3rd set of agreements here), click on the title to go to the MTDSG/UNTS record page.

The depositary is required to provide treaty related information to all interested parties on the treaties deposited with him. The Secretary-General, as depositary of multilateral treaties, provides this information by issuing depositary notifications. Depositary notifications might be in regard to:
The database may be browsed or searched.
The Certified True Copies Database contains PDF version of the Certified True Copy (CTC) of each of the multilateral treaties for which the Secretary-General is a depositary (so-called ex-officio multilateral treaties). The CTC includes the treaty translated into all the official languages of the treaty.
For most research purposes, it is not necessary to consult a CTC, as the UNTS reprints the text of the CTC.
The CTC database may be accessed by browsing or searching.

Multilateral and bilateral treaties are not always deposited with the UN. Sometimes they are deposited with other international organizations. The depositary is one of the places to look for updated status information and subsequent treaty actions (such as conferences of the parties). Remember, a treaty might be published in UNTS but deposited with another international organization or individual country.
Even when a treaty has been deposited with the UN, it is sometimes faster to locate relevant treaty information on a specialized website with more specialized information.
Below are just a few of the most frequently used online treaty collections.
The World Intellectual Property Organization (WIPO) is the United Nations agency dedicated to the use of intellectual property (patents,copyright, trademarks, designs, etc.) as a means of stimulating innovation and creativity. Their mission is to promote innovation and creativity for the economic, social and cultural development of all countries, through a blanced and effective international intellectual property system.
In service of this mission, WIPO administers the intellectual property treaties. The treaty page contains convenient links to the relevant treaties and helpful interpretive information.
The ILO is the international organization responsible for drawing up and overseeing international labour standards. It is the only 'tripartite' United Nations agency that brings together representatives of governments, employers and workers to jointly shape policies and programmes promoting Decent Work for all. This unique arrangement gives the ILO an edge in incorporating 'real world' knowledge about employment and work.
To facilitate this work, ILO provides NORMLEX, an information system on International Labor Standards.
The National Law Center for Inter-American Free Trade is affiliated with the James E. Rogers College of Law at the University of Arizona. The Center is dedicated to developing the legal infrastructure to build trade capacity and promote economic development in the Americas. The Center has developed the NatLaw World Legal Database of laws, regulations and secondary source materials for several countries in the Americas. This database includes a collection of treaties, free trade agreements, and international agreements affecting the Americas. The database contains English translations of many important treaties,supplementary treaty material, and links to other sources of treaty information.

EUR-Lex provides free access to European Union law and other documents considered to be public. The website is available in 23 official languages of the European Union. The contents of the site amount to some 2,815,000 documents with texts dating back to 1951. Among the documents found on the site are an extensive collection of Treaties and International Agreements.
http://eur-lex.europa.eu/collection/eu-law/treaties.html
The Treaty collection from the European Commission complements the treaty collection on Eur-Lex. It contains all the bilateral and multilateral treaties or agreements concluded by the European Community, the European Atomic Energy Community (EAEC) and the former European Coal and Steel Community (ECSC), and those concluded under the Treaty on European Union. Agreements signed but not yet in force are identified by an asterisk (*).
The Database does not include the “founding treaties” of the European Community and European Union or other agreements concluded between the Member States of the European Union, as these are found in Eur-Lex.
