What to do with old LP inner sleeve?


I've begun to purge my older vinyl collection to only keep the near pristine ones and now I find myself at a crossroad as to what to do with the older inner sleeves that have advertisement on them.  I'm talking about the ones where the companies like Verve, Columbia, to name a few, that advertise with the pictures of albums of other artists on their label.   They have no liner notes or lyrics, just company promo.   Do these sleeves add any value to the LP should I decide to sell it to another collector?  I'd much rather throw them away, as it makes it a slight bit tighter with the replacement sleeve which has more layers.  What is the general consensus amongst you all?

In terms of collectability or monetary value, the original sleeve adds nothing, unless it is particular to the record. Standard printed company sleeves are utterly worthless. Blue Note sleeves included. That being said, I always keep original sleeves with any vintage record that I obtain, printed or no.
One thought...

If it's a record that's played 'semi-often', substitute a generic sleeve for the original.  Store the originals in a file, labeling same as to what it goes to.

In that way, the sleeve is spared the wear 'n tear of the old in 'n out.  Old paper is old paper after all, and time doth take it's toll...

Or, better...dup it if it's a real collectible.  Play the original only when you 
Absolutely Have To.  Entropy is inevitable....
Thank you all for your input.  It was much helpful.

psag, a question for you, if you don't mind regarding vintage records.  What year, generally, would that classification start?  1940's, 30's, or earlier?  And would any year for LP's fall into that category? Thanks.
If the original ad sleeves make too tight a fit, sometimes I slide them in the outer sleeve behind the album cover. Those old ads are an entertaining read sometimes. It's not every day that you can read promos for England Dan & John Ford Coley! Cheers,

If you like an old musky smell along with incubated mold spores, go ahead and keep those old inner sleeves.
