The InterNano Nanomanufacturing Repository (INR) is a central repository of nanomanufacturing research and trade information for the nanomanufacturing community. It is administered by the National Nanomanufacturing Network (NNN) and funded by the National Science Foundation through the Center for Hierarchical Manufacturing at the University of Massachusetts Amherst. The INR is unique even as a central repository because it crosses not only institutional boundaries but also sector boundaries by including reports, research, teaching aids, and grey literature relevant to nanomanufacturing from academic, government, and industrial entities. In addition, because nanomanufacturing is itself inherently interdisciplinary, the repository crosses domain boundaries by including work that ranges from chemistry and physics to sociology and ethics. The INR is still early in development. Reflecting the two essential approaches for nanomanufacturing itself, the NNN is employing both top-down and bottom-up activities to build this national repository. Now in the "bottom-up" stage, the INR uses EPrints as its most fundamental building block and has incorporated a novel taxonomy and collections structure to support nanomanufacturing information. The NNN has customized the EPrints interface to reflect the InterNano Nanomanufacturing Clearinghouse, which the INR is designed to support. In addition, the NNN is manually migrating and soliciting content from its affiliates to build collections. Looking ahead to the "top down" activities, the NNN will be implementing an OAI harvester and initiating a SWORD pilot project to facilitate the deposition of relevant content from the vast body of nanotechnology literature. This presentation will describe the INR project with attention to its unique content, taxonomy, and customizations to the EPrints standard interface.
