The wide-ranging selection of periodicals (yearbooks) and collection editions (inter alia commemorative publications) in international law available at the Library are continuously evaluated and classified by the research staff. The evaluation of journals was ceased at the end of 2018.
The articles' classification is divided into three sections. The evaluation of comparative and municipal law was discontinued in 2010.
Classification of periodical and monographic literature dealing with public international law was also published in the bibliography "Public International Law (PIL)". The printed edition ceased publication with Vol. 41 (2015). By using the PIL classification the content (1996 - 2010) can still be searched via the Institute's OPAC.
