Do library managers practice better knowledge management than any other type of managers?

In his excellent paper, Ferguson, discusses some challenges I was thinking about. He shows some similarities between Information Management and Knowledge Management and suggests that it is better for library and information professionals to involve in KM from their IM skills and applying KM for their libraries rather than claiming to be their organization's knowledge manager.
Below is some extracts from his paper:

• We should be asking whether the KM principles that some see as integral to librarianship are actually practiced in our libraries.
• There is no empirical evidence to suggest that library managers practice better KM than any other type of manager.
• Library managers whose ability to leverage the intellectual capital of their libraries leaves considerable 'room for improvement'
