paste meaning in Information Science terminology / glossary / dictionary is:
A type of adhesive used to stick together lightweight materials such as paper and gold leaf, made from the starch contained in a cereal grain such as wheat, corn, or rice, combined over heat with water (and sometimes alum or resin) until smooth, then allowed to cool. Paste is used to affix labels and bookplates because it is water soluble, making them easy to remove if necessary. However, water solubility also makes it susceptible to mold. Because it is made from a vegetable substance, paste also attracts insects that damage books. Compare with glue. See also: cut-and-paste.
