Selection criteria for digital resources

The collection field of online publications covers all text, image and sound-based works made available on public networks. The submission obligation covers both Internet publications with corresponding printed versions and also web-specific media works. Examples of online publications include electronic magazines, eBooks, university dissertations, digitised content, music files and also websites.

Generally only formats are accepted that allow a digital long term preservation.

Temporary pre-publications, pure software or application tools, and radio and TV programmes are not collected.

Online publications which only serve private or commercial purposes are not collected either. This basically means websites consisting e. g. of private photos and descriptions of holidays which are only of interest to private individuals, or presentations of a company's goods and services which are only relevant for customers.
