When initially issued the stories were not numbered and the publisher showed the list of available stories in the “Assignment” series in alphabetical order though often the alphabetical list did not include all of the previous stories. Later re-prints numbered the stories based the order in which they were first published though the list of stories just before the title page was still in alphabetical order. The list is shown in numbered/published order here. Each story is a standalone work and while they can be read in any order reading them in the order given here will provide some continuity as there are occasional references to people or incidents from previous assignments.
