158.723 Meaning: Dewey Decimal?
Today I was browsing the 'post secret' website and I found an interesting number: 158.723.
The secret was supposedly posted by a librarian and it was basically a picture of a book page that said: "I have a case of 158.723 and it is turning me into the kind of librarian that I hate."
Does anyone know the meaning of the number 158.723?
I couldn't find much information about it on the web. I believe it is a dewey decimal but I'm not sure. What is the meaning of 158.723?
