For the record

■ Correction: Because of a photographer’s error, a caption on the front of Sunday’s Metro section, accompanying a story on Boston University reacting to the deaths of three students studying abroad, misspelled the name of Jeremy Butz, a water polo player at the school.

■ Correction: Because of a reporting error, a story about “Avenue Q’’ in Sunday’s Arts section misidentified the Puppet Showplace Theatre in Brookline.

■ Correction: Because of a reporting error, a story in the May 1 Metro section and the accompanying headline incorrectly described the 1894 document that was purported to list Elizabeth Warren’s great-great-great grandmother as a Cherokee. The document, alluded to in a family newsletter found by the New England Historic Genealogical Society, was an application for a marriage license, not the license itself. Neither the society nor the Globe has seen the primary document, whose existence has not been proven.
