Additional documentation will be released in this section of the home page as 
the NDLP continues its work in the coming years.    
 
Documents recently released and available on the web include the two-part 
report about the NDLP which first appeared in the D-Lib electronic magazine at 
the CNRI website, "Historical Collections for the National Digital Library: 
Lessons and Challenges at the Library of Congress", and a report prepared for 
the NDLP by the Image Permanence Institute (James Reilly and Dr.Franziska 
Frey), entitled, "Recommendations for the Evaluation of Digital Images 
Produced from Photographic, Microphotographic, and Various Paper Formats."  
This report discusses approaches to evaluate the performance of scanning 
service providers and the measurement of capture resolution and tonality by 
interpreting or reading test targets.  The American Memory SGML Document Type 
Definition (DTD) and the Encoded Archival Description homepage were also made 
available this month.

Previously released information includes a discussion about the American 
Memory Pilot Project, various American Memory Technical Papers:  "Elements of 
Digital Archive Collections", "Frameworks and Finding Aids: Organizing Digital 
Archive Collections", "Reproduction Quality Issues in a Digital Library 
System" and also the proceedings of the Workshop on Electronic Texts held at 
LC in 1992.
