whats the best way to reglue record covers

I've always found "Duco Cement" to work well. It's a multipurpose household glue, but it seems to work extremely well for both record covers and split book bindings. Readily available at most hardware stores.

I use my kid's school glue sticks. They work very well.

I have used glue sticks with good results as well. No mess, put tht glue right where you want it.

When I ran my used LP store I invested in a double sided adhesive tape gun, not sure if they are still available. It would be the same thickness tape as the inside lip of most LPs(especially European covers)except the hard cardboarded original 60-70's LPs from the US. I found this to be the best method no mess with glues etc and least impact on the covers themselves.

I use contact adhesive like uhu or evostik.
