The selection and use of procedural and declarative information in software manuals

Some research results suggest that declarative information in a software manual is of little value to a user. However, most research methods are aimed at measuring specific information effects. They hardly ever yield data about what users select and use if they have a choice. Also, the concepts of procedural and declarative have not been operationalized consistently. Finally, one type of user has been the main focus of investigation so far: the tutorial user.
