Did you ever wonder how we know where to find things on the library shelves? The SVC library, like many libraries all over the world, uses the Dewey Decimal Classification system (DDC) to organize our resources.
Before Melvil Dewey standardized things in 1876, different libraries organized their materials in very different ways. Even within one library there would be different systems, sometimes even just by just adding new books to the end of the collection or sticking them on a shelf where they fit.
Books were often just assigned a number according to the order in which they were acquired. or where they were on the shelf. Then Dewey came up with a system where a number corresponded to a subject area. This allows a user to look in one area for all the books on a particular topic.
Dewey's use of decimal numbers means the DDC is infinitely expandable. For example, he created a category for nursing, but he had no idea we’d one day have simulation technology. A decimal system allows for subdividing existing categories and adding new numbers.
