Explanation of the Search Fields
Each study is assigned a title that is usually derived from the documentation or other print information. This title may include descriptive words indicating content, geographic focus, chronological year(s) of coverage, source of information, major sponsor, and sequence numbers.
The abstract field contains a brief summary of a research study. It includes the research focus and a description of what kind of data were collected.
The Principal Investigator is the person, persons, or agency responsible for the dataset's intellectual content or for initiating the study.
The producer field contains information similar to the publisher of a book. The producer is the person or agency with financial or administrative responsibility for the physical processes of creating the data file. The producer field includes the place of production, the name of the person or agency, and, when known, the date of production.
Many of the files in the Data Archive have been acquired through Cornell's membership in the Inter-university Consortium for Political and Social Research. If we obtained the data from ICPSR, you can use the ICPSR-assigned study number to search for the study.
The Data Archive assigns its own codebook numbers for each study or group of studies that use the same documentation. These "numbers" consist of a mnemonic for broad subject categories (e.g. ED for Education) and a number. You can browse a list of subject categories and codebook mnemonics to become familiar with our classification system.
