The Information Services Department (ISD) (simplified Chinese: 政府新闻处; traditional Chinese: 政府新聞處) is the Hong Kong Government's public relations consultant, publisher, advertising agent and news agency. It is the link between the administration and the media. It therefore tries to enhance the public understanding of government policies, decisions, and activities.

Prior to the current location at the Murray Building, ISD was once headquartered at the Former French Mission Building and at Beaconsfield House.

The department is organized into four divisions:

An information broker, also known as an independent information professional or information consultant, is a person or business that researches information for clients. Common uses for information brokers include market research and patent searches, but can include practically any type of information research.

A Master's degree in library science (M.L.S.) or in library and information science (M.L.I.S.) is preferred or the norm. However, these prerequisites aren't always necessary. Some brokers have a master's or PH.D in law, social sciences or liberal arts.

In 1977 Kelly Warnken published the first fee-based information directory, which continues to be published and has expanded to cover international concerns. The Association of Independent Information Professionals, the first professional association devoted to information brokers, was formed in Milwaukee in 1987. The profession has its roots in 1937 when librarians and other information professionals formed an organization called the American Society for Information Science and Technology in an attempt to establish their professional identity separate from public libraries.
