From the IFLA (International Federation of Library Associations):
The survey, available online, was sent to several IFLA groups and many mailing lists for immediate release, and was also put out on the IFLA website. After preliminary results were drafted, several other national libraries were contacted, with requests sent out in other languages than English because it was noticed that there were few responses from some parts of the world.
The survey was primarily intended for national cataloguing committees, national libraries, and national, regional, or multinational rule-making bodies. The Survey Study Group intended that the responders should be institutions involved in creating cataloguing rules or in defining national profiles or procedures for their application. Probably the words “other interested groups” in the text of the distribution generated some misunderstanding since many responses came from other types of institutions such as university, special and even public libraries. Their responses are also included in the results.

There are some inconsistencies in the answers. Despite this, the results are very useful in order to draw a broad picture about the use of the ISBD and other rules or standards, and also about future directions.
