This annoted bibliography provides brief abstracts of publications dealing with synthetic polymers in conservation for the period 1966 to 1974. Publications are listed alphabetically by year rather than topically. Uses of polymers in making casts, restoration, stabilization and consolidation, and other kinds of conservation treatment are among the topics covered. A synthetic polymer subject index for both Supplement 1 (which appeared in AATA Volume 13, No. 1) and Supplement 2 (the present supplement), follows the abstract listing.
