A broken spine, loose covers, and ripped pages are unwelcome sights in anyone’s library. Thankfully, a simple roll of tape can assist with repairs. While it might be tempting to reach for whatever masking tape or cellophane tape you have on hand, you’ll achieve much better results if you purchase specialty repair tape that is stronger and stretchier to provide better protection over both level and rounded surfaces. These tapes also tend to be acid free, especially important if you’re fixing valuable volumes. Find the best tape for your needs—whether you’re patching up slim zines, heavy monographs, or beloved art history texts—in our roundup of favorites below.
