Surveys and comparisons are always very difficult, if not impossible, when the same criteria cannot be applied to all objects of the survey.
The surveys undertaken by Kurt Schwerin in 1960 and Igor Kavass in 1972 belong to this category of nearly impossible tasks and their results should therefore not be considered as the “absolute” or “pure truth”. Why? Basically, because they attempt to measure and compare collections in libraries which have different rules, policies and practices of classifying and handling them.
