After the death of a leading figure or great disaster, condolence books are placed in public places for members of the general public to use.
Reviewing a condolence book may help grieving relatives come to terms with the reality of their loss.

For example, after the assassination of Abraham Lincoln, the Government Printing Office published a leather-bound, gilt-edged collection of official condolences in 1867.
