The only thing more forlorn than the National Aquarium is the editing of Annys Shin’s “Underwater Dive” (1/5). The very first paragraph, the one that’s supposed to grab the reader, says the aquarium’s home is the “Department of Commerce’s J. Edgar Hoover Building.” A casual knowledge of downtown or 20th-century American history—or maybe even some basic fact-checking—would have determined that it’s the Herbert C. Hoover Building, named way back in 1982 after an obscure former president and Commerce secretary.
