You may easily manage your references using one of the reference management programs. Generally all citation managers offer a similar set of features making citing and creating reference lists for your papers as fast and simple as possible. Using them you may:

• collect and store your references in your own library,
• attach PDFs to references,
• generate citations and reference lists in your DOC or other format documents,
• refine collected data,
• sync references across all your devices.

The library promotes and offers help for Mendeley citation manager, but you may of course freely choose the software which best suits your needs. You may find the majority of available reference managers using detailed list provided by Wikipedia.

You may get all information about Mendeley and its corresponding apps download and usage here.

Keep in mind that every citation manager is only a tool and, when operating on incorrect data, may return incorrect reference. Always make sure the information you are collecting or adding manually is accurate and publication type format relates to actual publication type.
