The database can be browsed alphabetically. There are four sorting keys (options) provided:
- Bare form: The nominative case form of the surname minus all prefixes, articles and initial mutations. This is a novel gender-neutral form developed for this project.
- Base form: The male form of the surname in the nominative case.
- Ordinary form: The ordinary form of the surname in the nominative case, be it the male, wife or daughter form.
- Root form: The personal name from which the surname is derived. We use this as a lexical title for each surname cluster.
