I had the opportunity of visiting the High Density Storage facilty at Oak Street on May 25, 2017. What i saw from the outside was a very huge building and had no idea about the storage and its services.
It was indeed an impressing sight just to see millions of books piled up so neatly on the storage racks which was so high above. It was also amazing to know that these books can be retrieved within a few hours for delivery.
Visiting the storage facility highly impressed me and I am still wondering how the system works so perfectly!!!!
