The 9/11 Names Arrangement software is a custom software application for The 9/11 Memorial that assisted in determining the arrangement of the almost 3,000 names of the men, women, and children killed in the attacks of September 11, 2001 and February 26, 1993. The names are inscribed in bronze parapets surrounding the twin Memorial pools.
The Memorial Guide is a website, kiosk interface and mobile application that helps people navigate the 9/11 Memorial. It assists users in finding a name on the memorial as well as gives biological information of everyone killed in the attacks of September 11, 2001 and February 26, 1993. The Memorial Guide is further organized by "meaningful adjacencies", which reveal personal relationships that were requested by the families and next of kin.
