Abstract
This article amplifies an earlier article in this journal where the author described the programs of the Center for History of Physics of the American Institute of Physics (AIP). There emphasis was on the evolution of the AIP's national effort to improve the selection of materials documenting modern physics and allied sciences. The focus of Part II is on another aspect of the AIP Center's documentation strategy: the cooperative efforts to develop the International Catalog of Sources for History of Physics and Allied Sciences (ICOS) and the current project to extend the coverage of the ICOS and make it more widely available to researchers.
