Source-derived summary

Shedd Aquarium (formally the John G. Shedd Aquarium) is a public aquarium in Chicago, Illinois, United States. It is one of the oldest continually operating non-governmental aquariums in the U.S.

Opened on May 30, 1930, the 5 million US gal (19,000,000 L; 4,200,000 imp gal) aquarium holds about 32,000 animals. It is the fourth largest aquarium in the Western Hemisphere (after L'Oceanogràfic, the Georgia Aquarium and The Seas at Epcot) and the 11th-largest aquarium in the world.

The Shedd Aquarium is a highly ranked world aquarium and at one time was the largest indoor facility in the world. It is the first inland aquarium with a permanent saltwater fish collection. The aquarium is located along Lake Michigan in the city's Museum Campus, which also includes other highly ranked institutions such as Adler Planetarium and the Field Museum of Natural History.

In 2015, the Shedd Aquarium had 2.02 million visitors. It was the most visited aquarium in the Western Hemisphere in 2005, and in 2007, became the most visited cultural institution in Chicago. The aquarium contains 1,500 species, including fish, marine mammals, birds, snakes, amphibians, and insects. The aquarium received awards for "best exhibit" from the Association of Zoos and Aquariums (AZA) for Seahorse Symphony in 1999, Amazon Rising in 2001, and Wild Reef in 2004.

Editorial summary

The public source identifies “Shedd Aquarium” as public aquarium in Chicago, Illinois, United States. This brief keeps that definition visible, then builds a research path around Shedd, Aquarium and public.

Editorial reviewA dependable orientation record for establishing vocabulary, names and a first evidence trail. The current lead gives the account dated anchors—1930, 2015, 2005, 2007—that can be checked directly. The authority record carries competing date values—1930-05-30, 1930—which should remain separate until their references and qualifiers are resolved. Its value is orientation rather than verdict, with Shedd, Aquarium and public providing the first useful test.

Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
