Outer Vinyl Sleeves, is it a good idea?

I've tried many different products and methods over the years. Sleeve City sells these 5.0 mil polypropylene oversized outer sleeves, which are large enough for a double album. They present like mylar- hard and clear. I package the jacket and inner separately within the outer sleeve for a couple reasons. One, it reduces wear and tear on the jacket. Two, it reduces the friction involved in removing the sleeved record from the jacket. Friction yields static. I protect the backside of the package with either a generic paper and HDPE inner or a stiff generic white outer jacket that has a label hole so I can see the record. I also insert any original printed inner that has artifact value in this package. If it is a high value record or double LP set, I'll often package the jacket separately from the record(s) and use the same outer jacket and generic outer jacket with hole cut out to separate the records, using the original inners as another layer of protection between the sleeved LP and the jacket. 

I've never had a problem with mold- which is usually the result of dampness. Occasionally, I'll go into the "stacks" of less played records in an adjacent room and pull out a record I haven't played for 30 years. It will usually be in one of those old VRP sleeves from Discwasher--a highly regarded aftermarket inner from the late '70s-early '80s. Those were likely cleaned on a VPI eons ago and in some cases, I don't even bother re-cleaning them using my current methods.

The "package" approach I use takes up more room. But I've found it the most workable, and since I reduced my record collection to around 5.5k records--I can accommodate most of the high value, most interesting ones in my main listening room. Part of the process is also organization. Everybody has their preferred method. I separate the jazz from the rock, and all the classical except for a few that are "in play" are in my adjacent room- alphabetized and in some cases, grouped by label. Most of the old "audiophile" and direct to disc stuff from decades ago is in the second room-rarely gets played but grouped together largely by label. 

Some of the most collectible stuff is grouped by label- Vertigo Swirls have a shelf; Strata-East and private label jazz has a shelf; otherwise, the jazz is just alphabetical even if a mix of high value OGs and newer remasters. The trick is being able to find a record easily. I'd prefer a face forward storage method but don't have enough space for that so its spine out. But organization helps as does leaving enough space in each shelf to thumb through the records. 

@lewm- my terminology probably wasn’t consistent either, does this  help?

@wrm57 - I wish I could take myself seriously. I’m really a dilletante with a lot of different interests. Lately been focusing on motorsports again after a long hiatus.  

FWIW, after trying virtually all the different inner sleeves available including the MA Records product, I'm using the Japanese round bottom ones- they seem to shed the least. 

@bdp24 - if it is the same guy I’m thinking of, he owns an ad agency in Germany, was involved in the whole MoFi debacle a few years ago where everybody was named "Mike"--the In Groove guy who did the expose, this guy, Fremer, and even that OCD Mike guy of Interwebs fame (at the time when there was a flurry of posts about the issue, it was the four "Mikes" which made me laugh). I don’t usually watch web-based talking head stuff--I will resort to YT videos where a manufacturer shows how to do something with one of their products.

Plus, if it is the same fellow, I also thought he got rid of all his new MoFi records that were pulled from DSD "masters" and got into buying up OG pressings, but haven’t followed him. 

@lewm- I use the method but not the product BDP24 describes, and yes, it makes for a thicker package even when using a simple oversized outer jacket without an extra pocket, shown in that photo I posted upthread.
