Abstract
A document sorting process utilizes existing or natural incoming sequences of documents each of which includes a sort key code thereon and which are sequentially arranged in accordance with a trace, locate and retrieve number (TLR). The documents are machine-sorted by the sort key code in numerical sequence and the corresponding trace, locate and retrieve number is checked for ascending or descending order. Whenever the trace, locate and retrieve number is seen in ascending order, the created sort number remains the same, whereas on a descending record the sort number is incremented by one digit. A reduction in the number of sort numbers reduces the passes required for physically sorting the documents.
