DPLS News April 1993 Are You a Data CREATOR? Are you a researcher whose projects result in machine-readable data? Based on the premise that high quality data, once generated, should be fully and effectively exploited by as many researchers as possible, granting agencies such as the National Science Foundation, the National Institute of Justice, and the Department of Health and Human Services now require researchers to archive data collected as a result of funded projects. The DPLS has a long tradition of assisting investigators in the production and preservation of public use files that will facilitate the dissemination and utilization of their data by other researchers. Over the last 25 years the DPLS has acquired, processed and preserved many high quality datasets generated by investigators on this campus and around the world. These include: Dynamics of Idealism: Volunteers for Civil Rights, 1965- 1982, Occupational Changes in a Generation, 1962 and 1973, Census and Property Surveys of 15th Century Italy, and the Wisconsin High School Student Panel Study of Social and Psychological Factors in Status Attainment, 1957 and 1964. Additionally, if you have purchased data for your own purposes, and would like to make them available to other users on this campus, DPLS is happy to make copies of both data and documentation and place them in the library. In this manner we have added many important studies to our collection. If you are interested in receiving information on how to produce public use files, or would like to submit data for inclusion in the DPLS data archive, please give us a call. Are You a Data User? The creation of a dataset that is properly documented and usable by other researchers deserves recognition in the same way as a printed work of scholarship does. You should undertake to acknowledge both depositor and archive in any published work arising from the analysis of such data. The best way to do this is to cite the dataset in the same way as you would cite a printed information source in a bibliography - no data source should be described within the text of an article without appearing also in the bibliography. Failure to cite datasets means that valuable data sources will not be indexed by bibliographical services such as social science citation indexes. More importantly, other researchers who would like to analyze these data may not have sufficient information to acquire them. For more information on citing data, or to see examples of proper citation, see a librarian at DPLS. Data on CD-ROM Available at DPLS Crime and Justice Data. This disc contains 24 datasets, including National Crime Victimization Surveys (1987-1989 Incident File and the 1989 Full File), Law Enforcement Management and Administrative Statistics (1987), National Jail Census (1978, 1983, 1988) and Survey of Youth in Custody (1987). These files are in ASCII format and come with SAS and SPSS setup files. The documentation is in machine readable format. National Longitudinal Surveys of Labor Market Experience (NLS). This project began in the mid-1960s to collect information about four population cohorts in the U.S.: the Mature Men, 1966-1991 (45 to 59 years old in 1966), the Mature Women, 1967-1989 (30-44 in 1967), the Young Men, 1966-1990 (14 to 24 in 1966), and the Young Women, 1968-1989 (14 to 24 in 1968). The data on this compactdisc include cohort information about work experience, military experience,training, schooling, family background, marital status, income and assets,health, fertility, child care, discrimination, household responsibilities,volunteer activities, health insurance and retirement plans, and experience. National Longitudinal Survey of Youth (NLSY). This disc contains two files,Youth 1979-1990 and their Children 1986-1988. The youth cohort is a nationalrepresentative sample of 12,686 young men and women who were aged 14-21 in 1979in their first interview. The yearly surveys of NLSY chronicle their majorchanges such as: finishing their schooling, moving out of their parental homes,making decisions on continued education and training, entering the labormarket, serving in the military, marriage and starting families of their own.NLS old cohorts and youth cohort discs both come with a retrieval program whichallows you to pick and choose variables and download them to a floppy disk. NLSY Work History Data. This dataset contains a week-by-week longitudinalwork record of each NLSY respondent from January 1, 1978 through 1990. It hasover 7,650 variables. The record layout for CD-ROM is binary format. Thereare sample programs in C and Pascal to read the data off the disc. International Financial Statistics Data. This CD-ROM subscription providesusers with time series data covering approximately 26,000 economic conceptswhich show major economic aggregates used in the analysis of economicdevelopments. Its topics cover the balance of payments, banking and financialsystem, employment, exchange rates, fund position, government finance, interestrates, international liquidity and banking, national accounts, population,prices, production and trade for over 200 countries. It is updated monthly.Users can select different time series and download them in Lotus, ASCII Formatted Text or WordStar text formats. Panel Study of Income Dynamics. The PSID is a longitudinal survey of a representative sample of U.S. individuals (men, women, and children) and thefamilies in which they reside. This study emphasizes the dynamic aspects ofeconomic and demographic behavior and also contains sociological andpsychological measures. Its data can be used for cross-sectional, longitudinaland intergenerational analyses and for studying both individuals and families.DPLS currently owns two CD-ROMs containing PSID 1968-1988 data. Because thesedata are in ASCII format you need commercial statistics packages to do data extraction. DPLS staff have put together a sample SAS program to show you howto do the extraction. CD-ROMs from Other Campus Libraries. Users can check out any of the followingCD-ROMs, bring them to DPLS and use our 486 work station to read data off thedisc. Data on these CD-ROMs are often in raw ASCII format; you need to usestatistical packages, such as SAS or SPSS (available via the Novell networkfrom SSML) to extract data off these CD-ROMs. What follows is a short list ofthe CD-ROMs that can be acquired from other libraries: Schools and Staffing Survey, 1987-1988.

Search Public Opinion Poll Questions. The Institute for Research in Social Science at UNC-Chapel Hill is the repository for both Roper Center and Louis Harris survey data. They have created an online *public opinion item index: which allows question-level searching of Louis Harris Polls, the General Social Survey (1972-1991), USA Today Polls, Latin American Public Opinion, and a few other polls. By searching on question words, you can generate an item list which contains the question, the percentage responses, as well as some of the sampling information. There are menu options for e-mailing results, although using your *print screen: key works easily for a short search. (Note that the entire dataset is not accessible for analysis.) To access: You must be able to use Telnet 3270, which allows emulation for an IBM mainframe. The Social Science Micro-computing lab's Novell menu offers this option. The internet address is: UNCVM1.ACS.UNC.EDU. Login using IRSS11, IRSS12, or IRSS13. The password is IRSS. Press return until you see *Running: displayed in the right lower corner. Choose the Public Opinion Item Index from the menu and follow instructions for searching. Consortium Data at Your Fingertips.
