=== Early Bird Registration === The International UDC Seminar entitled "Classification & Authority Control: Expanding Resource Discovery" will take place in The National Library of Portugal in Lisbon, on 29-30 October 2015. Conference website: http://seminar.udcc.org/2015. Contact: seminar2015@udcc.org Linked data practices and techniques have opened new possibilities in exploiting controlled vocabularies and improving resource discovery. Authority data held in library systems often includes classification schemes. These knowledge structures now have the potential for being shared across the linked data environment. The objective of this conference is to explore such potential, expanding the value and use of classification as an authority controlled vocabulary, from a local perspective to the global environment. The conference will be opened by Emer. Prof. Michael Buckland, well-known expert in the history and theory of documentation and bibliographic access. The topic of authority control, subject authority control and subject access in various contexts will be discussed by a series of eminent speakers speakers including Barbara Tillett, Dagobert Soergel, Rebecca Green, Maja Zumer, Marcia Zeng, Nuno Freire, Andrea Scharnhorst, Maria Ines Cordeiro, Koraljka Golub, Claudio Gnoli.
