These files contain materials relating to Lieberson's last decade at the firm (c. 1965-1975), when he served as a member of the Board of the Columbia Foundation, Inc. (CFI). The documents range from board meeting notes (compiled in large folders, organized by meeting date) to correspondence and inter-Columbia business memos dealing with matters relating to the board or to the larger corporation. In general, these business materials differ from other Columbia business files in that they involve memberships and donations relating to CFI, not to Columbia Masterworks or Columbia Records. For correspondence and materials relating to recording projects, the researcher should consult the Columbia Projects sub-series or the correspondence series.
