The cost and funding studies project of the proposed Western Interstate Bibliographic Network began activities in July 1975. Major activities during the third quarter included: (1) renaming of the program to Western Interstate Library Coordinating Organization (WILCO) to reflect the facilitating and coordinating role anticipated for the entire program; and (2) commencement of the Survey of Costs in Technical Processing and Interlibrary Loan, involving cost data collected in 100 libraries in 17 western states and British Columbia. The appendices which form the bulk of the report contain the program outline, definitions of sample strata for the Survey of Present Library Costs, analysis of the sample and response rate, and case study data collection activity sheets.
