It is difficult to keep this database up to date. The stream of research on happiness is growing while our capacity remains limited (See the organizational basis of the project). At this moment the findings of some 500 studies on happiness are waiting to be entered in the database and the waiting list is growing every day.
Hence we welcome financial support. With some extra money we can hire smart students who can help us to keep this database up to date.
