Album cover repair-Help

Thank you all for your help. I now have
a host of options to try (and not try!)

I use a special tape from light impressions that is archival. you can reverse/peel it off with heat and it doesnt stick or leave residue

Here is some very good info:

white glue works well along with glass wax for covers...you could also use book binding material on the inside not outside. A cheap way is using construction paper with white glue on the inside of the cover.Cut the paper in 2" width and length of the jacket fold the construction paper and slide it inside and glue it dries fast and its neat.
