The Library of Congress's discussions with 3M vis-a-vis CDs is that they have tested their adhesive "on their CD products, but not on CDs from other manufacturers." Thus, since 1. no specific testing has been done on accelerated aging and effects of security strips--3M's or others--on stability of a wide range of CDs from varying sources and qualities; and since 2. the lacquer layer of CDs (the label side in most/all? cases for published CDs) is well known to be especially susceptible to various acids (remember the problem with inks a few years back); the Library of Congress has decided that no label or marking should be put directly onto the surface of a CD which is intended for longterm storage or use. We are attempting to locate an alternative marking/securing device for CDs. If you have solutions that work for you or suggestions of same please let me know.
