In September 1990, the U.S. Department of Education's Library Technology and Cooperation Grants Program awarded a three‐year grant to the Florida Center for Library Automation (FCLA), an agency of the Florida State University System, to develop software adhering to the ANSI Z39.50 Information Retrieval protocol standard. The Z39.50 software was to operate over the Open Systems Interconnect (OSI) communications protocols and be integrated with FCLA's NOTIS system, which is shared by all nine state universities in Florida. In order to test the correctness of its Z39.50 software, FCLA sought out other library software developers who would be willing to develop Z39.50 systems of their own. As part of this process, FCLA helped to found the Z39.50 Implementors' Group (ZIG), which has since gone on to improve the standard and promote Z39.50 implementations throughout much of the North American library systems marketplace. Early on in the project, it became apparent that TCP/IP would be a more heavily used communications vehicle for Z39.50 messages than OSI. FCLA expanded its design to include TCP/IP and, by the end of the grant in September 1993, will have a working Z39.50 system that can communicate over both OSI and TCP/IP networks.

The objective of OSI conformance testing is to provide a standardized and rigorous means of determining the extent to which a specific implementation conforms to an OSI protocol specification. As part of its ILL Implementation Program, the National Library of Canada has developed a test system and service for the interlibrary loan (ILL) protocol using the ISO standard methodology for conformance testing (ISO 9656). Development of test suites, conformance testing tools, and conformance testing services are presented. The article also discusses related topics such as interoperability testing, arbitration testing, and international harmonization of conformance testing.

X.400, one of the first OSI Application layer standards to be ratified, has generated considerable interest in the computer and telecommunications industry. Software vendors and network service providers are now marketing X.400‐based products. Message handling systems based on X.400 support interpersonal electronic mail services and also provide a generic mechanism for the exchange of information between computer systems. This ability to support information transfer between computer systems is the real contribution of X.400. Telecommunications based on this standard can be applied to library operations such as interlibrary loan, acquisitions and document delivery.

This special “theme” issue of Library Hi Tech is devoted to Open Systems Interconnection. The editor is Ray Denenberg, of the Library of Congress. Eleven articles cover the basic OSI platform, applications, support areas, and implementation. The basic OSI platform consists of protocols for the seven layers, including support for file transfer and message handling. Three articles describe network applications and the corresponding OSI services and protocols. “Information Retrieval as a Network Application” describes the ANSI Z39.50 protocol. Another article describes the interlibrary loan protocol, which incorporates the sequences of messages that occur in distributed interlibrary loan transactions. An article about electronic data interchange describes the edi conceptual model being developed by ISO, and its relationship to OSI. Network management and directory services are two of the most important OSI support areas; individual articles cover these two topics. Implementation topics include profiles, testing, and products.

Describes a number of experiments with electronic document delivery, and the copyright problems that are affecting its use. Considers the inadequacies of interlending for the user, the interlending in Eastern Europe and Australia. Outlines the impact of CD‐ROM on document supply and suggests that interlending can be a social, cultural and economic measure.

This paper aims to understand the experiences of disabled doctoral students at one Aotearoa New Zealand University, identifying barriers to accessibility and meaningful participation, and enabling practices.

This research was underpinned by the social model of disability and used an explanatory sequential mixed methods approach. A survey comprising closed and freeform questions was distributed to all doctoral students. From the 64 respondents, 12 also took part in an unstructured, narrative interview. Data were analysed using a combination of methods: descriptive statistics, thematic analysis and poetic inquiry.

Findings are presented mainly as data poetry. The poems centre on complexities faced by disabled doctoral students, and articulate challenges, enabling practices and possibilities for the future encountered by students in this study. Findings are additionally supported with quotes from narrative interviews, open-ended survey questions and descriptive data analysis.

The poetic inquiry approach gives voice to the collective experiences of disabled students. The poetic texts bear witness to the intersections of disability, impairment, chronic illness, neurodiversity and doctoral study, and the lives of students who navigate these intersections. These poems voice and seek to be lightning-rods for social change.

In the matter of food purity and control Hospital Catering Services have been outside the law, a privileged position where the general law of food and drugs have never applied and the modern regulatory control in food hygiene has similarly not applied. In the eyes of the general public hospital catering standards have always been high above the general run of food preparation. As the NHS continued, complaints began gradually to seep out of the closed community, of dirt in the kitchens and prevalent hygiene malpractices. The general standard for most hospitals remained high but there were no means of dealing with the small minority of complaints which disgusted patients and non‐cater‐ing staff, such as insect and rodent infestations, and an increase in the frequency of food poisoning outbreaks.

AS one of the most important parts of an aeroplane, an airscrew must be designed L in such a way as to prevent all avoidable risk of damage. Serious danger may be incurred, by vibration of the airscrew as it revolves. Up to the present, relatively few publications of practical value have appeared which deal with the calculation and observation of airscrew oscillations.
