%0 Journal Article %T The LIBER Security Network of 2002 ¨C The Copenhagen Principles %J Liber Quarterly : The Journal of European Research Libraries %D 2002 %I %X The last decade has seen the rapid development of a number of factors affecting the security of significant library collections. The market value of large parts of library collections now equals the prices of the most expensive antiques and works of art; The interest of the free market in items held in libraries is constantly increasing; Valuable parts of library collections have been subject to grave instances of theft of a trans-national character across Europe. Recognizing these developments, we have decided to set up closer co-operation among libraries with the purpose of preventing or resolving such incidents. %U http://liber.library.uu.nl/index.php/lq/article/view/7699
