A prophetic knowledge of the future development of libraries would no doubt give large significance to certain omitted items. Direct access to very early reports of certain libraries has been impossible, and these reports have been examined for the indexer by persons connected with those libraries. In a number of instances full information could not be obtained. In addition to the list of libraries indexed there is given an alphabetical key and a list of abbreviations used.
