7. GeoRef • Serials Issues Study • The percentage of items obtained from the USGS dropped from 48% in 2000 to 38% in 2006 • Items obtained directly by AGI grew from 13% in 2000 to 24.5% in 2006 • The amount of metadata delivered electronically by publishers almost doubled, but remains relatively small at 7% • International Indexing Projects account for almost 30% of all issues obtained in 2006

8. GeoRef • Initial Comments • Direct AGI acquisition of sources has counterbalanced some of the reduction in sources from the USGS library (Grew 11.5%) • AGI obtains 55% of its materials from the Web. What are the implications of this for specific segments of the literature that are going missing? Gray Literature? Conference Proceedings? • International Partnerships have grown to fill other coverage gaps • The International publications represented by these partnerships are increasingly unavailable in US libraries. Is GeoRef doing enough to insure future availability?
