We are a collaborative project with 8 Swedish municipalities where public libraries, school libraries and high school libraries are in the same database and share the same catalogue. Reservation collaborations in similar constellations often mean that public libraries borrow from each other but not from school libraries. Despite this, all these units are lined up in the same organizational structure in Quria and when searching, the large number of school libraries can make it difficult for librarians to see which books are in which public libraries (and vice versa).
My suggestion is that it should be possible to set the LIBRARY TYPE in the system settings. On this page you can fill in any values, such as "Public Library", "School Library", "Court Library", "Whatever".
Under Organization Settings, you should be able to specify which unit is one of the specified, above mentioned, Library types.
This is then intended to be used primarily as a filter when performing searches (or perhaps even in a statistical context?) in Quria. You can set your hit list on the basic organizational structure that Quria has today, as well as "filter by Library type". In this way, users will become more observant of which books are in or can be reserved at their library type that share the same reservation cooperation. Noise in hit lists must strive to be decreased to a minimum, and this becomes even more apparent as more and more municipalities see benefits of merging into a joint databases (like ours).
