The Study skin compactors had 11 rows, numbered from a to k. In our example, our shelf is in the last row of the Study skin compactors. This means that our location code is now:
land vertebrates store/study skin compactors/k
The cupboards within each row are also given a unique number - in this example we had a sequential number ranging from 1 to 66. These cupboards are classified as 'bays' within our location scheme, and our shelf is in cupboard #61. This means that our location code is now:
land vertebrates store/study skin compactors/k.61
Now the real fun starts - creating the shelf numbers! In our location system, the shelves are always numbered from the floor upwards. However, the shelves are not numbered sequentially (i.e. shelf 1, shelf 2, shelf 3...) as this could cause headaches when we need to add extra shelves into existing sequences.
Instead, we name shelves using the number of shelf bracket spaces between the floor and the shelf. For example, in the image below of a cupboard in the study skin compactors, we have four shelves, numbered shelf 2, shelf 7, shelf 10, and shelf 16.
