Outer Vinyl Sleeves, is it a good idea?

I tried that and probably hundreds of others have too. In my opinion, the results did not adequately compensate for the annoyance. Nor have I ever perceived that significant dust accumulates on an LP via the open end of an album cover.  If that’s a problem , just rotate the inner sleeve so the naked edge of the LP is not exposed. Also, consider reducing dust in your listening room.

My entire collection resides in the Japanese Resealable Outer Sleeves that are sold by Elusive Disc.   I've never had a problem with mold. 

These Sleeves are perfectly sized in that they will accept singles, and even all doubles and some triples fit. They are durable, crystal clear, the adhesive strip does not fail.   I've always been 100% satisfied with them.

Beware of others, the ones MusicDirect sell are not the same, are inferior IMO, and they're even too small-tight for just singles, let alone doubles.

@porchlight1 - I've slid the outer sleeve over the open end for years, ever since I tried it the other way and it was a real bear getting them into and out of my LP shelves without the sleeves wanting to remove themselves....  

I had a house flood in 1985 (I posted on this elsewhere today) .  I tried saving my LPs for a few years because I couldn’t afford to buy any kind of replacements until the ex demanded that they go. I had mold everywhere, on the album covers, inner sleeves, the LPs…Now if I go to a record store to browse and there is the slightest bit of mold I am out of there pronto.

Weird how many people have mold issues. Never seen a moldy album. But have see a ton of dirty, scratched and nasty album covers. Think if mold is an issue you should have desiccant around your collection!!!

Not sure if they use it anymore, but the old plastic that albums used to come with can leach onto the album. I was told to always remove the plastic they come in. Just paper, or cardboard sleeve just scratch and imbed stuff on the records. So don't use them either. 

All my records have proper inner and outer sleeves. Have tried a few places, but MoFi makes great ones, as does Vinyl Storage Solutions. Anytime there is a sale, I just stock up, usually getting a few hundred at a time. Have a bit over 3000 records. 

It does help keep them clean, easy to slide in and out, keeps the jackets pristine. When storing records, I put the outer sleeve pointing up, this allows you to slide the album in and out of the rack without the sleeve coming off, or jamming. Also put the  sleeved record in the back of the album jacket on the outside, but inside the outer sleeve. Albums never fall out, are very easy to remove for play. It also allows me to never have to remove the sleeves, will never damage the record jacket, trying to get the record in or out of it.
