A company called American Tombow has two that were new to me. Both dry clear. The MonoMulti can be used as a permanent hold glue or applied so that it gives a temporary bond. Similarly, one of American Tombow's new roll-on adhesives affixes permanently, and another lays down a sticky line whose hold is only temporary. Although you could dispose of the dispensers when the supply runs out, I highly recommend that you don't discard them.
Refills are available.
Refills are also available for 3M's new adhesive dispenser. It is larger in size than that from Tombow, and the strip of adhesive it lays down is slightly larger, but it serves the same function. For those of you who are concerned about using non-acidic glue in your memory books, I've been told that are safe to use. It is usually the tape that is the troublemaker and not the adhesive.
