With the increase and the variety of vehicles being built, it became clear that one owner could not get every kind of car, but sharing inventory with other salvage yard owners would help both owners sell more parts. Originally this was done with “long lines” a predecessor to the modern computer. People call in looking for a part, if you did not have it you call out over the lines in search of the salvaged auto part, and if a fellow salvage yard had the part they call you and everyone makes a sale. This method was effective, but the modern computer has turned the salvaged auto parts industry into a multi-billion dollar industry. With the introduction of the world wide web, if you know where to look you can easily find almost anything you are looking for and keeping track of not only your inventory but many others as well.
