It is important to know that a researcher does not necessarily have a status that recognizes the specificity of his work. A researcher is someone whose professional function is to contribute to the production of scientific works: books, novels, collections of poems, pamphlets, short stories... He/she may not have the rank of researcher, but may be considered as such by the community. He may be a volunteer member of an association or an NGO, an engineer in a high-tech company or a member of a research laboratory.
