This session will provide a practical demonstration of a web resource, the ESRC Question Bank (Qb), which displays survey questionnaires and methodologies. In the past year the Qb has undergone extensive redesign to improve its usefulness. This demonstration will have two key aims: firstly to examine what the Qb is and how it may be used in conjunction with other data resources, secondly to show how it may be used to examine different questionnaire documentation styles and make comparisons between them. Two particular issues arising from the facilities in CAPI programs (mainly Blaise in the UK) will be discussed:nbsp; routing and control checks. The variety of solutions to the problems of reporting these functions adopted by survey agencies will be highlighted. This will be interpreted from the viewpoint of the secondary analyst, making clear the need for DDI standards in this area.
