Digital Libraries and the Internet Digital libraries in the context of this paper means any collection of digitised material. Many of these are available commercially under license or as pay as you view for those potential users for whom no licence has been purchased. Others are completely free
Publishing tradition Printed journals – articles were found through Word of Mouth until Abstracting and Indexing Services developed Replaced by e-journals which are more accessible In UK digital > print :: 25% > 75%; 45% of HE library budget goes on journals How has shift to digital been achieved? Internet protocols and PDF
Standards that enable the DL Anglo-American Cataloguing Rules ISO 2709: record structure for MARC, UNISIST Reference Manual, CCF
Successful standards PDF 1.7: Portable Document Format, part 1 (ISO 32000-1) COUNTER Common Command Language for Online Interactive Information Retrieval ANSI/NISO Z39.58 Commands for Interactive Text Searching (ISO equivalent) Boolean and or not and codes for data (ti for title)
Key standards System Data Sharing MARC (identifies fields and ISO 2709 is the record structure) Cross System Searching Z39.50 – Information retrieval (identifies indexes)
Standards makers ISO NISO BSI BIS React to professional bodies
NISO most active library technical services; the acquisition and management of e-resources; library systems implementation including ILS, ERMS, link resolvers, and web interfaces; cooperative electronic arrangements with other libraries, consortia, or content providers; or long-term preservation activities.
COUNTER – Counting Online Usage of NeTworked Electronic Resources Codes of practice for Journals/Databases and Books and Reference Works COUNTER-compliant reports are formatted exactly as defined in the COUNTER code of practice Usage
SUSHI The Standardized Usage Statistics Harvesting Initiative (SUSHI) Protocol – Z39.93-2007 – an automated request and response model for the harvesting of electronic resources Delivers reports formatted in XML
Identification ISO/DIS 26324, Digital Object Identifier (DOI) ANSI/NISO Z39.71 Holdings Statements for Bibliographic Items ISO 10324:1997 Information and documentation -- Holdings statements -- Summary level Implementation of holdings in XML:ISO 20775:2009 and documentation -- Schema for holdings information
Reporting holdings Data may be dispersed in several locations such as a union catalogue, local catalogue and a policy directory or repository. Standards for this purpose include: NCIP for local holdings XACML and LDAP for policy, authentication and authorisation information and SRU and Z39.50 for all types of searching and retrieval.
Open URL OpenURLenables the transfer of metadata about an item (a journal article or book, for example) from a resource, where a citation is discovered to a link resolver. Link resolvers direct users at particular institutions or organisations to appropriate, subscribed resources for the content, be they in electronic or print form.
This solves a critical problem for librarians Direct URL linking from one publisher’s content to another’s, including CrossRef DOI-based links, has the potential to lead users to resources that are inappropriate for them, i.e. to instances of content to which their institution does not subscribe. OpenURL overcomes this
Reporting holdings NISO developed SERU: A Shared Electronic Resource Understanding. The SERU Recommended Practice document (NISO-RP-7-2008). SERU offers publishers and librarians the opportunity to save both the time and the costs associated with a negotiated and signed license agreement by agreeing to operate within a framework of shared understanding and good faith. Among the issues covered in the SERU best-practice document are perpetual access, target6 groups of readers, archiving, and interlibrary loan.
