Is there a use for every item in Skyrim?

If you can pick it up, you probably need it.

But seriously? Unless it has no interesting value, leave them be. You'll get one when you need one.

Some items that seem useless at first do have a hidden use.

For example, ruined books can be used to create summon Atronach spell tomes

Once you learn Telekenesis you can 'use' all objects as projectiles.
