All softwares are tools that you use in managing your references. Just choose one from the selection, use and stick to it. Its better you master in using one, its application and trouble shooting

Hi Seema, There are lots of well developed software packages that will do this for you. EndNote RefWorks and Menedeley are just three. Your Library supports a number of these packages. Help is close to home. Look here to see where to start [ http://library.sdsu.edu/guides/sub.php?id=237 ]

Thank you Matt, its strange I have over 40 papers and couple of book chapters and I never used these tools...high time I should use..

You can use any one of many. I do prefer Endnote as it's easy to handle, fast processing, easy to share your library with your friends. But most importantly please make sure which refernce manager has been using by your labmates or your supervisor or your colleague. If you are the only one who is going to use endnote amoung your surrounding mates, then preferable to go with their software as u can always ask for help from them regarding that particular reference manager. If you are using different one than ur mates, then sometimes you will face problems to share your reference library with others, edit others' papers and be edited by your boss. 

There is also zotero in such softwares (shown in the link given by matt). In MS word it is also possible but not very practical to save a list of references in xml format or to transform a bibtex file into a word xml using the software jabref.

There is also free reference manager software called Mendeley, it has many tools to manage reference papers and also helps to add in our paper.

I have used mendely, zotero, refwork, endnote, jabref but I prefer Mendely. Its free, user-friendly and has many more applications rather then simple Referencing software. for e.g.

1. you can share formated library with PDF with your collaborator  : For instance you are working on particular review or research on particular topic and you are about team of 4-5 researcher. Then what you have to do is create share folder and invite your collaborator to join that folder at the same time 4-5 peoples can add PDFs and references to that folder If any duplicate references is found then it will recognized and it will merge with the original one by this way you can collect literature very effectively in shared folder one you feel that you have enough number of references just create bibliography using word plug-in then check all references wheather there is any error or  not for e.g. Journal Name, Volume No, Issue, Doi etc and in the case of Book, details about Author, Editor, Publisher, Place etc. Once you have complete library then Design first draft of paper in Microsoft word and circulate that file to your collaborator for completion of specific section 

There's Typeset which formats entire papers to journal-specific guidelines in seconds, including references.
