When asked “What kind of hole – holes dug by children in the sand for amusement, holes dug by gardeners to plant lettuce seedlings, tank traps, holes made by roadmakers?” he would reply indignantly that he wished for a general theory that would explain all of these. This man’s achievement has passed totally unnoticed except by me.’

- 10. A library asinstitution Because the purpose and result of absorbing information is always finally to produce further information, i.e., to continue the conversation, the function of the library must be understood as one that assists members of the community both in taking particular positions and in recognizing and assessing the positions taken by others.

- 11. A library asinstitution We often hear it said that libraries (and librarians) select, organize, retrieve, and transmit information or knowledge. That is true. But those are the activities, not the mission, of the library. … the important question is: "To what purpose?" We do not do those things by and for themselves. We do them in order to address an important and continuing need of the society we seek to serve. In short, we do it to support learning. Robert Martin.

- 15. The difficulty increating a digital management strategy stems in part from the bewildering convergence of technological developments. Developing a digital management strategy is further complicated by the fact that there are no recognized patterns or models for managing digital assets. Some managers seek to develop fully distributed institutional repositories but still must choose between open-source solutions or commercial providers. Others prefer to place their material in one of a limited number of dedicated storage institutions. While best practices may exist for given technical processes, library managers do not have a single paradigm to use as the basis for developing operational plans and policies to capture, store, index, preserve, and redistribute the intellectual output in digital formats.

Editor's Notes
- #7 Digital libraries – a wide range of services are digital-library-like. The involve selection, curation and disclosure of digital materials for particular audiences. Depending on your definition some of these are in, some out. Wherever you draw the line there is significant activity. ‘ Business’ – many organizations do digital-library-like activities to support their business needs. For example, think what will happen with historical collections of media materials in the ‘media’ business; collections of business documents (insurance, cheques) and so on in financial services companies; e-learning repositories; developing research collections. Digital library research reaches into many disciplines. Although there is a somewhat diffuse community of ‘digital library researchers’ in computer science, library and information science, and related issues, those who are building digital libraries are potentially interested in a wider research hinterland. This means that ‘digital library’ relates to a very diffuse set of interests.
- #8 I will focus on libraries!
- #14 Not clear how extensive the survey was or what the population was.
- #15 Amazoogle – from a policy and funding point of view libraries are increasingly working in an environment shaped by expectations created by Google and Amazon. The library has to create the value case in such an environment. User behaviors are changing in a network environment. Research and learning behaviors are co-evolving with general network activity. People create and consume information in new ways. There are no patterns for digital directions.
- #16 This may slightly overstate the case, but it is clear that we are some way from being able to routinely create viable digital information environments.
- #17 It is difficult to measure the impact of digital library research. It is clear that there have been local successes and one can point to certain outcomes which benefited from programmatic research funding. The ROI on user studies seems low. Many are tied to particular systems or services. Some commercial metasearch products have been assisted by being part of the EU technical research and development investment. OCLC Pica’s iPort grew out of the EU project Decomate. Fretwell Downing participated in EU and JISC funded activities which contributed to their current suite. IndexData did nice work in several EU projects also. Cheshire assisted by NSF funding. OpenURL and OAI – Herbert Van de Sompel.
- #20 Increasingly the library needs to provide services into the user environment – it needs to be visible in course management systems, in university portals, and so on. Not everybody will come to the library or to the library portal.
- #23 “economy of presence” – a phrase of Bill Mitchell’s. Users have heterogeneous requirements. What is an effective network presence.
- #25 ‘ below-the-line’ – i.e. below the line in the collections grid. These tend to be unique materials – special collections and research and learning materials (e-prints, data sets, courseware, …)
- #27 JISC has its Information Architecture and now the E-Learning Framework. These help us have conversations, create shared understanding, help us partition problems, and so on. The library community seems resistant to such shared architectures, which may be a good or a bad thing depending on your point of view.
- #28 Marchitecture – an architecture produced by a vendor for marketing purposes. May not be the best guide to the applications space. (do a search on google for more) Techeology – a mixture of technology and ideology. Discussion where ideological beliefs cloud technical discussion. I find this a useful word to describe quite a bit of the conversation one comes across. Portal envy – we must have a portal, everybody else does Beauty contests – discussion starts with which of the commonly known repository frameworks one wants rather than with requirements etc
- #29 Continued health of standards and OSS depends on intellectual and other contributions and sustaining frameworks. Mackenzie Smith spoke about difficulties with OSS at this conference. Neil McLean spoke about common services and the need for such infrastructural services. Again we are not sure how to secure and sustain these.
