(StringTypeLink["LibrarySystem", paclet:ref/entity/LibrarySystem]) entities include library systems that are sponsored by public institutions, such as state or municipal governments, as well as systems that are sponsored by academic institutions, such as universities.

(StringTypeLink["LibrarySystem", paclet:ref/entity/LibrarySystem]) entities are primarily institutions based in the United States.

Some properties are available for the (StringTypeLink["LibrarySystem", paclet:ref/entity/LibrarySystem]) entity type as a whole and can be given using the form (RefLink[EntityValue, paclet:ref/EntityValue])[(StringTypeLink["LibrarySystem", paclet:ref/entity/LibrarySystem]),property]. Such properties include:

The following annotations can be used in the third argument of (RefLink[EntityValue, paclet:ref/EntityValue])[(StringTypeLink["LibrarySystem", paclet:ref/entity/LibrarySystem]),property,annotation]:

The following annotations can be used in the second argument of (RefLink[EntityValue, paclet:ref/EntityValue])[property,annotation]:

A qualifier value of (RefLink[Automatic, paclet:ref/Automatic]) indicates that an applicable format of values can be used; e.g. for the "Date" qualifier, this includes a proper date or date span.
