A House of Commons committee rather than a single writer, this name belongs to the group appointed in 1849 to investigate Britain's contract packet mail service. The work captures a moment when Parliament was closely examining how overseas mail routes were run and how public money was being used.

by Peninsular and Oriental Steam Navigation Company, Great Britain. Parliament. House of Commons. Select Committee to Inquire into the Contract Packet Service
This author credit refers to an official parliamentary committee of the British House of Commons, not to one individual. In 1849, the Select Committee to Inquire into the Contract Packet Service was appointed to examine the government system for carrying mails by contracted steamship lines.
The committee's proceedings were published as part of Parliament's effort to gather evidence, question witnesses, and review the operation of the packet service. In modern library records, committee names like this are often listed as the author because the report was produced under the authority of the committee itself.
For listeners and readers, that means this is best understood as a piece of historical public record: a window into Victorian government, maritime communication, and the growing importance of global mail networks in the 19th century.
