The Travaux de L'Institut de Speologie "Emile Racovitza" is an interdisciplinary, peer-reviewed journal issued annually since 1962. The journal is a key publication for the research of the subterranean domain and karst systems. Initially published under the direction of Constantin Motas, the journal continued the direction established by Emil Racovita for the old series published under the Romanian title "Lucrarile Institutului de Speologie din Cluj". The "Travaux" new series publishes original papers by Romanian and foreign researchers in the fields of biospeleology and physical speleology.
