European Migration Network Glossary & Thesaurus

"The EMN Glossary improves comparability by enabling a common understanding and use of terms and definitions relating to asylum and migration. The Glossary draws on a variety of sources, but primarily on the legislation of the EU asylum and immigration acquis, and makes terms available in the majority of Member State languages."

International Thesaurus of Refugee Terminology

"The Thesaurus grew out of the Draft Thesaurus of Refugee Terminology compiled in English for the UNHCR by Piers Campbell in 1986. In 1988, the then chief of the UNHCR Centre for Documentation on Refugees (CDR), Hans Thoolen, invited Jean Aitchison, a respected expert in the field of thesauri, to provide the technical expertise for the revision and restructuring of this draft.
