	         gmd:Abstract:  
	
	            The International Polar Year Historical Data and Literature collection 
	            (formerly known as the Discovery and Access of Historic Literature from the 
	            IPYs (DAHLI) project) is an online data collection consisting primarily of 
	            photographs, publications, and observational data records from, and relating 
	            to, the first two International Polar Years (IPY) 1882-83 and 1932-33 and the 
	            International Geophysical Year (IGY)1957-58. Examples of data contained in 
	            observational records include, but are not limited to: air  magnetic vertical 
	            intensity, air conductivity, atmospheric-electric observations, auroral log 
	            data,  potential-gradient electrographic data, dust counts, and meteorological 
	            observations.  Photographs  within the collection include those from the 
	            Wilkes Station in Antarctica, the USGS survey of FletcherÂ’s  Ice Island, and 
	            the DTM Geophysical Laboratory Library.  Publications within this collection 
	            primarily  consist of government (national and international) bulletins and 
	            reports on activities during the  International Polar and International 
	            Geophysical years.  Other data include audio files of interviews  recorded 
	            during NCARÂ’s Oral Histories Project, and a video on Drifting Station Alpha 
	            during the IGY,  published by NSIDC.

Data were contributed by several 
	            institutions:  the University of Colorado Libraries, the Carnegie  Institution 
	            of Washington, National Snow and Ice Data Center (NSIDC), and The National 
	            Center for  Atmospheric Research (NCAR). 

The data collection contains 
	            approximately 800 digital objects, formats of these objects include:  PDF,  
	            TIFF, JPEG, MP3, and MPEG.  Most objects are freely accessible and 
	            downloadable, except where prohibited by  copyright.  

Temporal coverage of 
	            this data collection is between the years 1882 and 1958.  Geographical 
	            coverage  is global, with data originating from Europe, Asia, North America, 
	            and South America and relating  primarily to specific glaciers and other 
	            locations in North America (Alaska and Canada) and Antarctica.

All materials 
	            without use constraints are accessible by the public through the ROCS Archives 
	            Catalog.   Reference images and PDFs of publications and data are available 
	            for immediate viewing and download.  Please request high resolution TIFF image 
	            files through the Archives 
	            catalog.
