International organisations produce different types of primary sources. All of them can be used for research, although understanding their distinct characteristics is essential:
This broad category encompasses materials produced by governing bodies, conferences, and committees. These may include meeting minutes, resolutions, decisions, official correspondence, amendments, and formal reports. Official documents typically bear symbols indicating the issuing body, meeting, or decision reference. While access is sometimes restricted, they are generally public records maintained by libraries of international organisations.
This category includes official reports, statistical compilations, reviews, specialized studies, journals, yearbooks, and books. These publications usually carry ISBN or ISSN identifiers and are typically managed by libraries of international organisations. Today, they are increasingly accessible through online platforms.
This category consist of paper-based and electronic records preserved for their administrative, fiscal, legal, historical, or informational value. Unlike publications and official documents, archival materials remain unpublished and encompass diverse formats: textual documents (such us correspondence, memoranda, notes, draft reports and speeches), photographs, audio recordings, films, oral history projects, posters, and maps.
It is easy to get lost in the archives, so it is strongly recommended that you reflect on what you want to investigate before beginning your research. Your research question serves as your compass: it should be precise enough to orient your research while remaining flexible enough to evolve as you encounter new material.
Review the catalogue to understand what materials are available and in what formats (documents, audio-visual materials, posters, maps, recordings, etc.). This will help you identify relevant fonds, series, and collections, as well as potential search terms related to your research, such as specific terminology, names, dates, or decisions. Consulting the catalogue will also help familiarize yourself with the structure of the archives, the classification system, and reference numbers.
Access policies vary among international organisations, with restrictions ranging from 20 to 70 years. Some material might be submitted to special consultation rules, require special authorizations, or be restricted.
Depending on the type of archives, material may be available in different languages. Consider if language can represent a barrier for your research.
Archival research can be time-consuming. Do not wait until the last minute to start your research. In some case, archival materials may require special authorization to be consulted or are not stored onsite. Some archive services also limit the number of boxes that can be ordered per day. When you plan your research, be aware that visiting the archives can easily take at least half a day.
before planning to go in the archives, consult the official calendar. International organisations observe both local and international bank holidays. Moreover, reading rooms may be exceptionally closed for other reasons.
verify where the entrance to access the archives is located. Visitors’ entrance might differ from the main entrance. Remember to bring a valid ID. Today, most of the international organisations’ archives require scheduling an appointment and registering for access ahead of your visit.
always contact or talk the archivists before beginning your research. In some cases, it is compulsory. Most of the archives are open by appointment only (and you need to provide as short description of your research). In some cases, archivists can share in advance material (such as inventories) that might not be available online. Finally, they can also suggest material that you have not considered at first.
According to your research, going through your notes and your photographs can be time-consuming.
Consider carefully how yo the data you have collected from the archives. Consider if you need a long-term plan for storage (maybe for future projects). If you intend to delete the data, remember that deleting files is only the first step, and you will need to dispose of any confidential and sensitive data thoroughly, potentially through specialised software or safely disposing of any physical copies you have made.
Our libguide on Research Data Management can help you with this step.
Each archive has a different reference system. Consult the finding aids or ask an archivist how the material you are searching can be cited.
Archives services normally demand to be notified of the publications based on their resources. Do not forget to inform them when your work is published and, if possible, to share a copy.

Normally, you start your research by consulting a catalogue or an inventory.
Archives are hierarchically structured.
Collection: is a group of archives assembled by an archivist. In other terms, a collection is not directly created by an organisation or a person.
