What is "memorialising"

Usage examples of "memorialising".

One wall was shelved: tattered, leather-bound volumes of statutes and decrees, a handbook on forensic science, a dictionary, an atlas, a Berlin street guide, telephone directories, box files with labels gummed to them - 'Braune', 'Hundt', 'Stark', 'Zadek' - every one a bureaucratic tombstone, memorialising some long-forgotten victim.
