The subject groups are based on the classification system of Finnish public libraries. First choose one of the ten main groups. The subgroups of this main group will then show up.
When you click on the name of a subgroup, keywords related to the topic appear on the screen. These initiate the information search proper. The results are similar to those obtained in the Keyword search. You can remove the subgroups by clicking once again on the heading of the main group.
The links shown in connection with the subgroup take you directly to the web services related to the topic.
