For very many years now the SWF has been publishing ‘studies’. Because, in the past, they were printed and addressed to members at the same time as other news items, they were modestly called 'circulars', whereas in fact their scope, their importance and the permanence of their publication makes them hard to be considered as mere information bulletins for the members of the association.
These studies have increased in number and in variety, and a good many have been republished in a new digital format. As members are not always aware of the riches they represent, here, quite simply, is a catalogue of these recent studies, and bear in mind that older studies will soon acquire a similar lustre!
