Polysulfide instructions

I wanted to let you know that we have just completed a 12-page booklet,
"Instructions for Using IPI SilverLock(tm) on Silver Microfilm." This
publication brings together all the practical information on using
polysulfide treatment on microfilm, including how & why to treat,
frequency and nature of quality assurance tests, solution monitoring and
disposal, etc. We got a boost in creating this because Anne Kenney of
Cornell arranged for IPI to consult with vendors doing polysulfide
treatment in connection with Cornell's Southeast Asia microfilming
project. This helped clarify some of the practical treatment questions,
especially QA and also some of the administrative questions such as what
evidence should libraries require of filmers to show that polysulfide
treatment is being done correctly.

IPI will be glad to send anyone a copy of the SilverLock 
instruction booklet free of charge. Simply write to:
