This thesis deals with the question of why the Swedish Academy Dictionary has its own Library when, for almost a hundred years, it has been located at the University Library of Lund. Looking at the library functions: librarian, users, room and books and their external factors: economy, internal actors, external actors and the development of the Swedish Academy Dictionary helped to shed light upon which relations between these factors have been important in the development of the library. The results show that there has not been a conscious plan behind the Library. A large number of the books in the Library was given by those who have worked at the Dictionary and also by their friends and collegues. Another part was given by the Swedish Academy and was partly gathered when the project was still in Stockholm. Being so close to the books belonging to Lunds University Library has been a factor in not buying so many needed books, like expensive lexica. When the Dictionary moved from Lunds University Library a development into what can be described as a Special Library in Lexicology took place. One factor that was not considered but has proven to be important is the relation between the editors and other people in the society of Lund, and the desire to spread one's name.
