The URR allow association of most entries with reference to publications containing more in-depth information relevant for the entry. For this purpose, the URR integrates a very simple registry for references. The main attributes for an entry in this registry are the full reference according to a straight-forward format used by several scientific journals, a URL to a on-line version of the publication (if available), and an abstract/summary of the reference.
Before entering a new reference, it is recommended to first search the list of available entries to avoid duplicated entries. This list can be accessed by clicking on 'View all references'.
