Open Harvester Systems
Welcome to the Public Knowledge Project's metadata archive... To improve the accuracy of searching within the PKP System, authors have been asked to index their work, where applicable, by discipline(s), topics, genre, method, coverage, and sample. This allows you to search for "empirical" versus "historical" studies, for example, under "index terms." You can also view a document's index terms by selecting the complete record from among the search results.
