They represent an invaluable value. However improper restoration represents a significant problem for manuscripts and documents and sometimes leads to their loss. One of the most important improper restorations is the use of pressure-sensitive tapes. This study aims to present integrated research on the problem of using these tapes in all their dimensions and to provide solutions used globally in this field. The history of using the pressure-sensitive tapes, their structure, the effect of aging on different types of tapes, deterioration forms, and their deterioration mechanisms were well explained. Different techniques (The traditional and advanced techniques) used for the removal of these tapes were described. The results showed that both traditional and advanced methods removed the pressure-sensitive tapes and improved the surface of the deteriorated manuscripts. On the other hand, it can also be said that there are some disadvantages that can be obtained from the traditional methods, and many advantages that can be obtained from advanced techniques. The study also confirmed that the choice of the technique used to remove pressure-sensitive tapes depends mainly on the state of the manuscript or the document itself.
