Selection criteria

Development of new media like Internet and World Wide Web confronts the libraries with a challenge to identify, catalogue and preserve the Internet resources. Similarly to the traditional resources, the National and University Library in Zagreb is responsible for collection, description, storage and providing access to web resources as an integral part of national cultural heritage.
Web resources differ from the traditional publications in many features: frequent change of location, content and size, short and unpredictable life cycle on the Internet, and so on. With the aim to save these resources for the posterity the National and University Library in Zagreb, in cooperation with the University Computing Centre (Srce) created in 2004 a system for archiving Internet contents – Croatian Web Archive.

General and specific selection criteria for cataloguing and archiving of web resources

General criteria

Same general criteria are applied to printed and web resources:

  1. Works by Croatian authors published in Croatia and abroad
  2. Works about Croatia and Croatians, regardless of place of publication and authorship
  3. Works on Croatia
  4. Works published in Croatia, i.e.:
    1. Place of publication on the resource indicates that it is created in Croatia
    2. Publisher’s residence in Croatia
    3. Author’s residence in Croatia

Specific criteria

  1. Content
    Refers to the presentation of data such as title and publisher/issuing body responsible for content and creation of publication, design and arrangement of menus and data, regularity of updating. (For more detail see Recommendations for the presentation of web resources).
  2. Publication structure
    Refers to the presentation of data such as title and publisher/issuing body responsible for content and creation of publication, design and arrangement of menus and data, regularity of updating.
  3. Publisher
    All content published on the Internet is considered to be published, and everybody who publishes is a publisher. These can be publishers in the traditional sense of the word, as well as authors of personal web pages.
  4. Domain
    Resources that are originally published on the .hr domain are primarily selected for the web archive. Resources on other domains (.com, .net, .info, .org) may be selected if they meet other selection criteria.
  5. Format
    The data format in which the resource was published, for example text processor (Word), portable document format (PDF), hypertext mark-up language (HTML). The Library collects, stores and provides access to publications in their original format. If the resource is published in several different formats, the Library selects the format that can be stored in the original form in order to keep the integrity and authenticity of the resource (appearance, design, search mode) and secure the readability of data. Standard formats have priority.

Selection of publications for Croatian Web Archive
