The regional collection of „Metel Ožegović“ Public Library is the most valuable collection in the Library, which was first presented to the public in 1968. From the first moment it strived to become one of the most complete and high quality catalogued regional collections by collecting materials, designing catalogues, by diligent and shrewd work of its librarians together with Vanda Milčetić, the library director at that time. The materials have always been collected and catalogued in a responsible and inspirational way. Despite some problems while collecting, selecting and cataloguing materials, which have been caused by their publication, shape and kind, the Collection has gained its irrefutable status both in the regional area and outside its boundaries. Since 2008 the Collection has been completed systematically by authors which have not been included in the collection so far as well as by works of already included authors. The materials have been collected by purchase, donations, presents and by researching history, culture and science unflaggingly in order to find as many regional items as possible. At first the Collection included 1,000 titles while today it amounts to 10,000 volumes, by cataloguing all kinds of materials which have been entered into several inventory books.
