Some have title pages, others do not. Some have clearly identifiable authors, others do not. The interrelatedness of these objects can be quite complex. Even the consistent application of the codes is, in itself, a non-trivial task. Yet, the catalog is the key to the library.
Relevant expertise includes a thorough grounding in bibliography and some logic.
By way of illustration, the Paris Principles 6 and Wilson 7 can be cited. In library management, a very heavy emphasis is usually placed on experience Management is not generally regarded as an activity for which the reading of a textbook provides any very adequate preparation, although there is little doubt that reading can be helpful, especially when done in conjunction with experience. This is true, more or less, of all fields of management. For these and related reasons, one tends to fall back on discussion, on the analysis of cases, and on attempts to transpose to library contexts what is asserted about management in other contexts. Yet, the management of library services should not be lightly dismissed.
