1Needleman, M. ; Bodfish, J. ; Rush, J.E. ; Stevens, P.: ¬The NISO circulation interchange protocol (NCIP) : an XML based standard.
In: Library hi tech. 19(2001) no.3, S.223-230.
Abstract: Describes the NISO circulation interchange protocol (NCIP) and some of the design decisions that were made in developing it. When designing a protocol of the scale and scope of NCIP, certain decisions about what technologies to employ need to be made. Often there are multiple competing technologies that can be employed to accomplish the same functionality, and there are both positive and negative reasons for the choice of any particular one. Focuses specifically on the areas on which the protocol would be supported. Gives particular emphasis to the decision to choose XML as the encoding technology for the protocol messages. One of the main design goals for NCIP was to try to strike the appropriate balance between ease of implementation and providing appropriate functionality. This functionality includes that needed to support both application areas that the committee could anticipate would use the protocol in the short term, and new applications that might be developed in the future.

3Needleman, M.: Z39.50: a review, analysis and some thoughts on the future.
In: Library hi tech. 18(2000) no.2, S.158-165.
Abstract: This article will examine the Z39.50 Information Retrieval protocol. It will look at some of the history of the protocol, its operation, and some of the major projects that have made use of it. There has been enough written (perhaps too much) about Z39.50 in the last several years so it is not intended to be a tutorial or detailed description of the protocol. The material that will be presented will try and put some context around the discussion. For those readers who are interested in delving into Z39.50 in a more technical manner, references to much of the material that has been written about it over the years will be provided at the end. Finally, the article will conclude with some thoughts on how technology and technological infrastructure have changed in the years since Z39.50 was initially developed and deployed, and where the protocol has so far lived up to its goals, and where it has perhaps failed to meet some of the high expectations that at least some people involved in the Z39.50 community held for it. The article will conclude with some of the author's speculations (and they are really no more than that) of what the future role of Z39.50 is likely to be.

4Needleman, M.: Computing resources for an online catalog : ten years later.
In: Information technology and libraries. 11(1992), S.168-172.
Abstract: In this article I will look at the changig computing resources required to run a large information retrieval system like the MELVYL system. I will give a historical perspective, examining the aerly days of the MELVYL system and how the system has changed in the last decade. I will also provide some perspective on how new technologies have affected large information retrieval systems and what technologies will be required of such systems in the future, as the demands and requirements of large information retrieval systems continue to mature to meet increasing user needs.
5Needleman, M.H.: Z39.50: new doors opening.
In: DLA bulletin. 12(1992) no.2, S.14,24.
Abstract: Further development has occured in the construction of one user interface to access a variety of remote information resources through MELVYL. DLA demonstrated Z39.50-based connections between the MELVYL system and 3 remote information systems; Pennsylvabnia State University's LIAS catalogue, UC Berkeley's campus-wide information system and the library catalogue at AT&T's Bell Laboratory in New Jersey. Discusses the Z39.50 protocol and the client/server model, the MELVYL system implementation and future developments

6Needleman, M.H.: ¬The Z39.50 protocol : an implementor's perspective.
In: Resource sharing and information networks. 8(1992) no.1, S.89-103.
Abstract: Describes the Univ. of California MELVYL(R) system and its implementation of the Z39.50 information retrieval protocol. Discusses some of the open issues involving the the protocol as well as some of its implications for the library and information world
