The literature upon which this survey is based covers the period from 1975 to June 1985 and was searched both manually and by computer. More than 100 articles and patents were examined, and of these almost half were singled out as meriting citation. Several recent surveys (1-7) can be identified as sources that provide a general overview of current peroxide bleaching practice as specifically applied to mechanical and chemimechanical pulps. Additionally, an article by Allison (8), although not intended as a review, nevertheless serves as one by virtue of the broad scope of its content. -- AATA
