third duplicate number disappearing from the system. Once you have your box numbers, create an Excel spreadsheet and use the box number as the identifier in the first column and then write or stick that unique number on the box. Add the relevant description, including any date or sequence ranges, into the spreadsheet beside the unique number for each box. With a sufficiently structured spreadsheet, a lot of time will be saved; when retrieving a box you will only need to search one unique number rather than multiple words and date ranges. Furthermore, time will be saved if you adopt a similar system to that which is used by large record centres for locations. Think about creating a simple location grid that has a number for each wall of shelving and another number for each section of shelving along the wall. You can also add a letter for each shelf if you like. If you do this, you can come up with a simple location code, such as 1-2-A, that will tell you the box is located on wall or aisle 1, bay 2, shelf A. Enter this location next to the unique number for that box and you now have a faster way of finding your boxes if you ever need them.
