You don't need to. The advantage of saving the bib file in the TEXMF tree is 
that LaTeX can find it without further path information. So if you have a bib 
file that is used for several books and papers, you simply need to add the 
name of the bib file to each of these documents, i.e.
\bibliography{mybib}

If you need the file only for a single document, you can as well save it in 
the document folder.

In this case, however, you need to add the absolute path to the \bibliography 
command, i.e.
\bibliography{my/document/path/mybib}
