Through the development of information and communication technology, the amount of information available in electronic form is also increased. Facilities such as museums, archives and libraries must adapt their services and the material they offer according to the needs of the user. Their services include creating new and transforming existing material into digital by using digitization process. Digitization is the transformation of analogue material into digital, this process aims to improve the activity of the information institution and to expand its holdings. The key objective of digitization is to protect the material, if the materials are electronically accessible to users, the original is better protected because its use is limited thereby reducing the potential damage. Institutions that decide for using digitisation must first and foremost have the necessary financial resources and trained employees, in order to successfully implement the whole process and to have the opportunity to acquire all the additional equipment for reading electronic documents. The digitized collection needs to be continuously expanded and improved. An example of digitized material is a collection of books on the Croatian Homeland War at the National and University Library in Zagreb, which was created by the separation of materials with the theme of the Croatian Homeland War in a separate collection in order to bring the users of the library and the public closer to the different aspects of the Homeland war. The collection of library materials is made up of digitized articles about the Croatian Homeland war in the period from 1991. to 1993. More than 3500 articles from the daily and weekly Croatian and foreign press have been digitised in the library, and a bibliography of articles "War in Croatia" was also prepared. Keywords:
