This paper describes the provision of a Web Services interface that will extend the possibility of machine-to-machine access to the zetoc current awareness service, within the JISC Information Environment and eScience applications. This bespoke interface includes open standard XML metadata for searches and responses where possible. Elements from the OpenURL XML metadata formats for journals and books are used to transmit the bibliographic citation information that is an integral part of a zetoc record for a journal article or conference paper.

Digital library users have to deal with many separate services. This paper describes efforts in the United Kingdom to use OpenURL technology to provide `joined-up' services. The focus is on zetoc, a national electronic service, which enables users to find references in a British Library bibliographic database. zetoc now uses OpenURL technology to provide routes to services, which might give users access to electronic full text versions of references they have found. Data is provided from two questionnaire surveys and an interview programme conducted to explore user responses to these services. These evaluation studies show that users want these integrated services and are extremely positive about them when they work. However, `joined-up' services depend for their success on the access rights that each user has to full text sources in their institution. As a result, the success level in obtaining full text varies considerably between institutions. Users in disadvantageous positions have expressed disappointment and frustration; the service may be regarded as a promise not fulfilled. The paper describes the development of `joined-up services' as a partnership at national and local levels.

zetoc is a current awareness and document delivery service providing World Wide Web and Z39.50 access to the British Library's Electronic Table of Contents database of journal articles and conference papers, along with an email alerting service. An experimental prototype version of zetoc is under development, based on open standards, including Dublin Core and XML, and using the open source, leading-edge Cheshire II information retrieval technology. Enhancements investigated in this prototype include request and delivery of discovered articles, location of electronic articles using OpenURL technology, and additional current awareness functionality including the exposure of journal issue metadata according to the Open Archives Initiative protocol. These experimental developments will enhance the zetoc service to improve the information environment for researchers and learners.
