This study aims to analyse the effect of brand interactions such as personal interaction, problem-solving, reliability and store physical appearance on channel loyalty and purchase intention in optical physical stores.

The hypotheses are tested through quantitative research based on a questionnaire with a sample of 414 respondents. Researchers conduct multiple regressions to analyse the data.

The findings reveal that channel loyalty and purchase intention are positively influenced differently. Person-to-person interactions play a vital role in both constructs (dependent variables). This study also offers relevant managerial implications and future research avenues.

Despite the relevance of purchase intention in the literature, almost no studies have been published about the intention to buy glasses in the optical physical stores, a relevant contribution this paper offers to the literature. The finding that the store’s physical aspect did not prove to be influential for channel loyalty is also an innovative and relevant contribution of this research.

Apesar da relevância da intenção de compra na literatura, quase não foram publicados estudos sobre a intenção de compra de óculos nas lojas físicas de ótica, uma contribuição relevante que este trabalho oferece à literatura. A constatação de que o aspeto físico da loja não se revelou influente na fidelização ao canal é também um contributo inovador e relevante desta investigação.

The distinction between digital and analog data, the specific advantages of analog storage and the use of optical discs to store analog data are detailed. The configuration and potential of Level One, Level Two, and Level Three laser disc systems are explained. Side bars address: 1) selection of display devices for use with laser disc systems, and 2) laser disc systems for accessing audio data.

The first videodisc was demonstrated in 1927. A brief history of the videodisc is presented, describing the three major current manifestations of this storage medium—read‐only, write‐once, and erasable. Read‐only became an important information delivery format in 1985. During 1986, write‐once will begin to have impact on libraries and information centers. The current status of this technology, the major corporations involved in the field, and the potential uses for various types of storage media are described. A sidebar discusses Geac's use of optical media.

A scenario is given of a possible library of the future. Such a library might have shelves containing talking books, video cassettes, computer programs on floppy disks and the entire contents of Chemical Abstracts and Encyclopaedia Brittanica on biochips. The catalogue of the library stock and the reference books might well be stored on optical disks and viewed on flat screens. Information on the classification scheme and how to use the collection might be provided by listening to tape recordings and voice synthesisers might inform borrowers where to return items. Robots collect these items from dispensers and replace them on the shelves. Each item in the library has a barcode which is scanned by a laser to provide details of loans/returns and patrons. Terminals linked to computers via satellites enable distant files to be searched on demand for information not stored in the library. Most of the journals taken by the library will be in digital form but a touch of a button on the terminal causes the images to be printed out locally. Fact or fiction? The paper goes on to describe some of the equipment that is currently available to them in the future (such as holography, robotics and satellites). Where we are now in terms of technological developments in libraries and information centres is discussed with reference to some actual projects such as Maggie's Place and Dave's Den. Finally, the impact of such futuristic, electronic libraries on the user as well as the librarian is considered.

The aim of legal deposit is to ensure the preservation of and access to a nation’s intellectual and cultural heritage over time. There is a global trend towards extending legal deposit to cover digital publications in order to maintain comprehensive national archives. However, including digital publications in legal deposit regulations is not enough to ensure the long‐term preservation of these publications. Indeed, there are many practical difficulties associated with the entire deposit process. Conceptsm, principles and practices that are accepted and understood in the print environment, such as publication, publisher, place of publication and edition, may have new meanings or no longer be appropriate in a networked environment. Mechanisms for identifying, selecting and depositing digital material either do not exist or are inappropriate for some kinds of digital publication. There is a great deal of work on developing digital preservation strategies; this is at an early stage. National and other deposit libraries are at the forefront of research and development in this area, often in partnership with other libraries, publishers and technology vendors. Most of this activity is of a technical nature. There is some work on developing policies and strategies for managing digital resources. However, not all management issues or users’ needs are being addressed.

Argues that the personal computer is dead as a workplace phenomenon. Suggests that the financial pay‐off associated with using personal computers to increase knowledge and worker productivity is no longer viable; and that leading‐edge organizations are in transition between the close of the PC era and the accession of the new age of value‐on‐demand interpersonal computing. Highlights failings of the personal computer paradigm including points such as: focus on the individual and the desktop is misplaced; and the PC paradigm is flawed because the world which spawned such thinking no longer exists. Concludes by providing an action plan for conquering the interpersonal computer interregnum.

Since no one can be sure of future scholars' needs, it is safest to keep a copy of everything published; that is the theory behind legal deposit. Electronic publishing threatens to throw this system into disarray. In the following I refer to some recent discussions of this important topic.

A proliferation of optical products has resulted from the need to find a replacement for microfilm for storing images, to improve mass data storage technologies and to gain control over the distribution of commercial databases. Developers of CD‐ROM products need to follow a strategy that includes the following principles: (1) Focus on innovation rather than the technology; (2) Determine customers' needs; (3) Become expert in the available technologies; (4) Make a commitment to excellence; (5) Prepare a strategic plan; (6) Get a head‐start on the competition. Companies that have already been successful in CD‐ROM product development include R.R. Bowker, Disclosure and General Motors. The chances for success are greater for companies that can introduce new products and services frequently. Several companies have developed families of CD‐ROMs with a common interface, giving multiple users access to the information at the same time.

The new electronics‐based technologies have proved so effective at automating information handling, in libraries as well as elsewhere, that it often seems difficult to believe that they have any fundamental limitations. Certainly, while the requirement remains that of handling information in traditional ‘computer’ forms, notably those of data and text, the potential of the electronics technologies is indeed almost limitless. But what about more complex forms of information, such as the real‐life documentation that every organisation, and in particular every library, has to handle in very large quantities? Increasingly, it is becoming clear that when it comes to automating the handling of these more complex forms of information, the electronics technologies themselves cannot provide anything like a complete answer.

Libraries that provide document delivery services have traditionally adopted new technologies to acquiring documents from or supplying documents to other institutions. Microfilm, photographic reproduction, electro‐mechanical image storage and retrieval, xerography, electronic order transmission, and document facsimile transmission are all examples of new technologies applied over the course of time to document delivery. Currently being considered as being applicable to document delivery is optical disc technology. The characteristics of optical disc‐based systems are discussed and compared to current document delivery systems. The future role of optical disc technology in document delivery systems is predicted.
