An edition, on the other hand, refers to a specific printing or version of a newspaper issue. Newspapers may have multiple editions throughout the day or week, each with the same content but potentially with some minor variations. These variations can include updates, corrections, or additional information that was not available at the time of the initial printing. Different editions may also be distributed to different geographic regions or target different readership segments.
So, while an issue refers to a specific installment of a newspaper with its own unique content and date, an edition refers to a particular printing or version of that issue with potential minor differences.
