I am a real pack rat and will keep anything and everything that I might/will someday need. However what I really want is to know categorically what items are nothing more than junk so that I can sell them immediately and keep my inventory and storage tidy and my caps high.
I realise it is easy to identify which items are needed for crafting recipes (see link below) but some items are needed for quests, side quests or minor requirments across the Mojave throughout the game.

Please note: this list refers to Fallout: New Vegas only; some of these items are useful/required in Fallout 3.
I will keep updating the list below if people can contribute by either telling me how an item on the list is not only junk or adding other things that are useless in New Vegas:
Here is what I have as "useless" items so far.

*Item has a limited use for a side-quest but is not required for the quest's completion: ie; Issac at Gun Runners requires 100 pieces of scrap at one point, where Tin Cans or Bent Tin Cans count as such scrap pieces, though they are otherwise useless and you can use other items such as Scrap Metal to meet the requirement.
Hope this list helps! Please reply if anything is wrong/missing or if you have any comments/ideas!
