Understafiing continues to be the most immediately serious obstacle 

 to giving the Institution better library service, based on orderly, well- 

 kept, and well-cataloged collections. With so many of the larger 

 decentralized units left without regular full-time attendants it is im- 

 possible to give proper custodial care and supervision of the books.
