A single, public website that serves as a repository for all congressionally mandated reports would make it easier for the public to discover what the government has learned using their tax dollars and help congressional staffers who need to access the reports for their lawmaker or constituents.
There are already ways for staffers and the public to access congressionally mandated reports. The House Clerk organizes all reports sent to Congress, and members of the public can request any agency records via FOIA requests.
