I am working in a small Library where books are catalogued using the Dewey decimal Classification system. I thought about recording books in an excel spreadsheet according to the shelf number + DDC # to bring together works of similar topics and provide the books with a physical address . Secondly, I wanted to record an E-copy for the books in the library so to do that I was thinking to create 10 folders labelled with the 10 classes of the DDC system and within each folder create other folders to include the division (ex. Class:physics Division: Fluid). The Disadvantages of my method is that I want to include the book also and not the class of books only + its time consuming for the number of books in the library. No interaction with the user). I am looking for a software that allows me to implement the above and handle borrow/withdrawal of books too.
