Course and reading-list internal IDs should be available via Analytics
Course-reserves data available in Analytics does not include
the unique 16-digit identifiers for course and reading lists. They are retrievable only via the API. This is adequate for operations dealing with a single course or reading list, but it would also be useful to be able to obtain, e.g., a listing of all
courses and their associated ID numbers for a specific academic year, lecturer or department, to facilitate batch operations.
On the other hand, the IDs for reading-list citations are available from Analytics (Citation ID),
but there is no field indicating to which course or reading list a particular citation is assigned.
