[Koha] Question about 'Dewey' entry!

[Yaogeng Cheng]

>I am not a librarian so hopefully someone will correct me - I think that
the physical 
>location can be specified/determined from the 'Dewey' entry???

Can someone tell me if this is the right way to do it? -- How to locate the
book/CD in the bookshelf when I find them by searching them in Koha web
page.?

If this is the right way to do it, How can I do it? -- where to input Dewey
entry and how to retrieve it?

Is this is not the right way to do it, then what is and how to do it?

Thanks
