Best Glue for LP cover seams?


Has anyone found an easily applied glue that works well for LP cover seams? All the ones I have tried keep coming unglued after a few weeks.. Thanks for your input.

UHU Office Glue Pen manufactured in Germany. Ideal for paper & cardboard. This pen can be purchased in the archival/scrapbook supplies ($6.00) @ JoAnne's along with Scotch acid-free clear tape($5.00).
I use Elmer's Glue. A thin bead of glue and a heavy old book placed on the seam for an hour holds the bond.
I second the glue stick. I have to buy a pack every year for my children as part of their school supplies. I've been using one for years and it works well 95% of the time (a few times needed a second application).
