He should be enough of a bookworm to have a decided taste and fondness for books, and at the same time not enough to be such a recluse as loses sight of the point of view of those who know little of books.
As the responsible head of the institution, he should be consulted in all matters relating to its management.

The most satisfactory results are obtained in those libraries where the chief librarian is permitted to appoint assistants, select books, buy supplies, make regulations, and decide methods of cataloging, classifying, and lending; all subject to the approval of the trustees.

Trustees should impose responsibility, grant freedom, and exact results.
To the librarian himself one may say: Be punctual; be attentive; help develop enthusiasm in your assistants; be neat and consistent in your dress; be dignified but courteous in your manner.

Be careful in your contracts; be square with your board; be concise and technical; be accurate; be courageous and self-reliant; be careful about acknowledgments; be not worshipful of your work; be careful of your health.

Last of all, be yourself..
