Should I use interleaving paper in flat-file cabinet drawers?

Yes, especially for valuable or archival documents. Acid-free tissue paper or glassine placed between document sheets prevents surface contact, ink transfer, and abrasion damage. It also makes individual sheets easier to separate without dragging one across another. For everyday working drawings, interleaving is optional; for archival or valuable original artwork, it is strongly recommended.
