The project described addressed the feasibility of assessing the impact on low-income persons of the "Green Pages" concept, which seeks to improve the accessibility of public, non-profit, and survival human service agencies and other community information by centralizing them in a single, easy-to-find location in the phone book. This study focused on 11 sites where Green Pages-type formats have been published in the telephone books for varying lengths of time. Data were gathered through open-ended discussions, personal interviews, and structured questions with directory users; in person and phone interviews with administrative casework staff from agencies serving low-income persons; personal and phone conferences with telephone company representatives; and personal and phone conferences with state utility regulatory commissioners and their staff. Analysis of the data showed a favorable reception by directory users and identified variables in implementation methods affecting the impact. This report describes the methodology and sampling, discusses methodological limitations, and presents highlights of survey responses, as well as a lengthy analysis of potential affect. Appendices provide a history of the Green Pages concept, its current status, an examination of secondary sources of information, reviews of related research by telephone companies, and a draft evaluation plan to determine the impact of the concept on both poor and non-poor users.
