The storage cabinet racks are sourced from discarded materials, and the discarding method usually involves dividing by era. We can differentiate the storage cabinet racks by era, meaning we can group books published in the same year (or a few years apart) together. There will be a large number of books from the same era, and then we will arrange them in sequential order. When storing the storage cabinet racks, no empty racks need to be reserved for the same era, thus eliminating the need for re-arranging and wasting space. The pricing for cultural relics display equipment, with labels for eras placed on the storage cabinet racks, allows the original archive material labels to be reused without any need for changes.
