As part of our activity we acquire raw data, from already concluded studies that may be interesting for further analysis. The depositors are mostly academic institutions as well as public and private institutions which gather data themselves. First we ask the authors of original studies to deposit their data in ADP. All material is described in an electronic codebook, where details needed for understanding the contents of the material and its use are documented. The descriptions are filed in a catalogue, which users may use via the Internet. In addition, a more detailed search of codebooks is enabled by NESSTAR, a special tool for viewing the contents of codebooks. NESSTAR makes it possible to tabulate and visualise data quickly and easily when the database is accessible. Upon written request, we pass the data on to the users.

If necessary, ADP contact potential depositors and helps acquire data from studies, which are not stored in our archives. We cooperate with institutions, which supplement our activity and provide data and services available from different scientific and geographic areas than those covered by ADP. Based on a special agreement, domestic users may access data in European archives, members of the CESSDA, through ADP.

We also provide expertise and advice in the field of methodology and statistics as well as perform statistical analysis on request.
