user-1: I'm a noob to PCB designing and electronic stuff. I want to design a pcb shield which is compatible with an Arduino mega 2560. I'm using Eagle CAD. I checked the sparkfun library but I couldn't find a way to design Mega Shield. Can anybody give me a library or any alternative way to do this?

user-1: Since you're new user, perhaps it's easier to take an existing project and modify it for your need.
For Eagle, examples can be found on Github.

However, due to recent developments in the PCB EDA world I would suggest you take a look at Circuit Maker. It's more fit for sharing an collaborating designs and libraries. You can easily fork an existing board and use their community parts repository.
