I would like to know if people have concrete suggestions about or know of bibliography or on line resources that describe how to keep track of the different data collected. For example, if collecting semistructured individual interviews, I usually have a digital audio file, a short questionnaire on additional data for each interviewee (or at least notes on basic things like gender, place the interview was done, other characteristics that are basic to the study), as well as some field notes about methodological details about how the interview went. If there is more than one fieldworker, they obviously can't repeat identification numbers for their interviews (so you don't have two or three labeled as "interview #1"). When analyzing the interviews, one needs to be able to correctly link the transcription to the short questionnaire, and to the methodological notes. Any suggestions would be appreciated.
