Yesterday I bought an Egg-Container for storing eggs in my refrigerator. While reading the flayer provided with I came to know a tip which I want to authenticate by an expert of food science. It says - For longer storage with sustained freshness, store eggs upside down (keep the wide side up and slim side down).

Do some body have any authentic reference to support the statement?

As an egg producer in the US I can say that what you call eggs "up-side down" is how we store our eggs. It really doesn't matter which end is up when you store them, but I would never store them in anything but the container they came in. Most companies are removing those egg storage containers that come with a refrigerator. Eggs will keep the freshest in the container they came in. Egg shells have many tiny pores and air can pass through the pores and that is what ages an egg. Odors can also pass through those pores and make an egg taste bad. An egg has a natural protective coating and some will remain even when washed in processing but will only help so much. Keep your eggs fresher longer by keeping them in their original container and keep them away from smelly foods, I store mine large end up but that's mostly from habit, wanting the air cell at the top, heavy end at bottom.

I have never read about this, Egg is stored upside down, I dont think so it does any matter,
It is the traditional way to store the eggs as small end at the top and and wide side at the bottom...
IS there any scientific reason behind all these???

Complementing Charles C. link. The air cell or "air pocket" as the article calls it always forms in the fat end because it has more pores than the other. This air cell forms because of the difference of temperature between the hen's body and the exterior creating a difference in pressure two. 

If you store the eggs small end up the air tends to go up, therefore it will separate the exterior and interior membrane of the egg increasingly and making bacteria penetration towards the yolk easier.

I work in an egg company, we make sure to storage the eggs fat end up in fact is a quality criteria for us. 

Also about the storage at home. We do not recommend to storage eggs in the fridge door. It is the place where the can crack more easily because of the constant movement and suffer temperature fluctuation. They should be kept in the original container (the carton absorves water and odor protecting the egg from moisture and strong odors from the environment)
