Locating and Using Archive Data on the CISER Research Computing System
This page tells you how to find information about data in CISER's archive and how to locate individual files. If you can't locate a specific dataset or one that meets your need, please contact the CISER Help Desk for assistance.
CISER's collection database allows you to identify a specific study and associated files:
- Search our catalog; for example, by title or title words, principal investagator, issuing agency, ICPSR number.
- Browse our catalog by subject areas, including 19 broad categories and 57 subcategories.
Data files, most documentation, and other files (for example, SAS, SPSS, and Stata programs) are housed on the CISER file server. Some data require facility with a statistical software package that can read and manipulate raw data files or software-specific datasets.
Following are different ways Cornell users can use or obtain data archive holdings:
Once you log onto a research server, archive files are located in the V:\ drive. For example, these files comprise the World Values Surveys (CISER codebook SIND-071):
V:\sind\071\da2790 data file
V:\sind\071\sp2790 SPSS program
V:\sind\071\sa2790 SAS program
Usually, you don't have to copy archive files to your own user space or a CISER research server to use them. Most documentation files can be viewed from their original location using Notepad, Wordpad, or the Adobe Acrobat Reader. You can read raw data files from their original location within your program (using the infile statement in SAS, the file handle in /name = statement in SPSS, or the use command in Stata). Here is a simple SAS program that extracts three variables from the World Values Survey data file:
infile 'v:\sind\071\da2790' lrecl=352;
SAS, SPSS, and Stata input programs can be copied to your own user space and edited, or you can cut and paste the needed sections as you write your program.
Current Cornell faculty, staff, and students can download most archive files to their own machines from links in our online catalog. Files are downloaded in ZIP compressed format. Use WinZIP, Stuffit Expander, 7-Zip, or similar utilities to open them.
The example below provides a non-working example of what the catalog file information looks like. The icon takes you to the Obtaining Data Archive Files from the CISER Catalog page, which describes this service in more detail.

The archive has printed documentation for most datasets: codebooks, data dictionaries, technical reports, and questionnaires. These are arranged according to an in-house subject scheme. You can browse our shelves, plus use the online catalog to find documentation for which we have no print equivalent. Archive copies are intended for on-site use only. You might also find copies at Cornell University Library locations or on the Internet.
We own selected datasets on CD-ROMs or DVDs. You can use the archive's catalog to find these. The following example illustrates a study owned on CD-ROM:
County and City Data Book 2000U.S. Bureau of the Census. Washington, DC : The Bureau, 2003 [producer]. Washington, DC: The Bureau, 2003 [distributor]. Files on CDROM#: 773.
Some may be borrowed for use outside the archive, others must be used in the archive on a public machine. Please ask staff for help with locating these items.
