The document discusses several key challenges for users of the Library of Congress: 1) Fragmentation across multiple sites and domains causes confusion for users about where to find different resources. 2) Users have difficulty finding what they need from the home page or when entering via search/deep links. 3) Many potential users never access the Library's resources because they are not easily findable. The document argues that improving findability and reducing fragmentation across the Library's online presence would help more users access and utilize its resources.
