The DL.org Virtual Reading List, which was compiled for the Autumn School in October 2010, offers a valuable web-based guide not only to key DL.org outputs, such as the DL.org Digital Library Reference and Technology and Methodology Cookbook, but also on foundational articles and papers exploring digital library developments by leading figures from Library and Information Science and Computer Science.
The Digital Library Reference Model, April 2011
The DL.org Digital Library Technological and Methodological Cookbook, April 2011
The innovative Cookbook comprises a portfolio of best practices and pattern solutions to common issues faced when developing large-scale interoperable digital library systems. The Cookbook is designed to facilitate the assessment and selection of the solutions presented, enabling professionals working towards interoperability to define and pursue the different steps involved. It provides:
This State-of-the-Art survey has been produced by the DL.org Working Groups as a starting point for their investigation into different perspectives on digital libraries’ interoperability, and is a work in progress.
A. Paepcke, C. K. Chang, T. Winogard, H. Garcia-Molina, Interoperability for digital libraries worldwide, Communications of the ACM, 1998, 41(4), 33-42,
This  paper presents a broad introduction to the issues of interoperability,  suggesting factors that may be used in evaluating related solutions and  providing an overview of solution classes. 
C. L. Borgman, Challenges in building digital libraries for the 21st century, Lecture Notes in Computer Science, 2002, 2555, 1-13
The author summarises the key-challenges of 21st century digital libraries taking into account the technical, social and organisational context.
IDABC, European Interoperability Framework for Pan-European eGovernment Services, v1.0, EC (2004)
This  document provides recommendations and defines generic standards with  regard to organizational, semantic and technical aspects of  interoperability, offering a comprehensive set of principles for  European cooperation in eGovernment.
M. A. Goncalves, E. Fox, L. T. Watson, N. A.  Kipp, Streams, Structures, Spaces, Scenarios, Societies (5S): A Formal Model for Digital Libraries, ACM Transactions on Information Systems (TOIS), ACM Press, 2004, 22, 270-312
The  authors propose the fundamental abstractions of Streams, Structures,  Spaces, Scenarios, and Societies (5S), which allow us to define digital  libraries rigorously and usefully. Streams are sequences of arbitrary  items used to describe both static and dynamic (e.g., video) content.  Structures can be viewed as labeled directed graphs, which impose  organization.
Tony Hey, Stewart Tansley, Kristin Tolle (eds.), The Fourth Paradigm: Data-Intensive Scientific Discovery, Microsoft Corporation (2009). Part 4 “Scholarly communication” 175-220
Increasingly,  scientific breakthroughs will be powered by advanced computing  capabilities that help researchers manipulate and explore massive  datasets. The speed at which any given scientific discipline advances  will depend on how well its researchers collaborate with one another,  and with technologists, in areas of eScience such as databases, workflow  management, visualization, and cloud computing technologies.  Research  is evolving from small, autonomous scholarly guilds to larger, more  enlightened, and more interconnected communities of scientists who are  increasingly interdependent upon one another to move forward.
Duncan Birrell, Gordon Dunsire and Kathleen Menzies, Online Catalogue and Repository Interoperability Study (OCRIS), Final Report (2009)
The  aims of this study are to investigate and report on the: extent to  which academic repository content is already held in library OPACs;  interoperability of OPAC and repository software for the exchange of  metadata and other information; various services offered to  institutional managers, researchers, teachers and learners respectively  by OPACs and by repositories; potential for improvements in the links  from repositories and/or OPACs to other institutional services, such as  finance or research administration; development of possible further  beneficial links between library OPACs and institutional repositories.
