    Abstract
    Purpose The purpose of this paper is to lay a theoretical foundation for identifying operational information units for library and information professional activities in the context of scholarly communication. Design/methodology/approach The study adopts a deduction-verification approach to formulate a typology of units for scholarly information. It first deduces possible units from an existing conceptualization of information, which defines information as the combined product of data and meaning, and then tests the usefulness of these units via two empirical investigations, one with a group of scholarly papers and the other with a sample of scholarly information users. Findings The results show that, on defining an information unit as a piece of information that is complete in both data and meaning, to such an extent that it remains meaningful to its target audience when retrieved and displayed independently in a database, it is then possible to formulate a hierarchical typology of units for scholarly information. The typology proposed in this study consists of three levels, which in turn, consists of 1, 5 and 44 units, respectively. Research limitations/implications The result of this study has theoretical implications on both the philosophical and conceptual levels: on the philosophical level, it hinges on, and reinforces the objective view of information; on the conceptual level, it challenges the conceptualization of work by IFLA's Functional Requirements for Bibliographic Records and Library Reference Model but endorses that by Library of Congress's BIBFRAME 2.0 model. Practical implications It calls for reconsideration of existing operational units in a variety of library and information activities. Originality/value The study strengthens the conceptual foundation of operational information units and brings to light the primacy of "one work" as an information unit and the possibility for it to be supplemented by smaller units.

    Abstract
    Purpose - The purpose of this paper is to examine the multifaceted information disadvantages facing the so-called information poor in today's society. It has two specific objectives: to identify, from the empirical evidence of individuals' daily and regular information practices, meaningful constructs for defining information inequality; and to investigate how the "information poor" characterise on these constructs in comparison with others. Design/methodology/approach - The study developed its findings in relation to the above objectives inductively from the interview transcripts of 73 people of different social statuses and occupations regarding their daily and regular information practices. Findings - Three concepts emerged as meaningful constructs to define information inequality, hence to describe the information poor: individuals' information resource bases, information practices, and information assets. The information poor are found to be disadvantaged in all these aspects. They are first disadvantaged by limited freedom and/or opportunities in claiming society's vast and rapidly increasing information resources into their own information resource bases; then by the constraint of their information practices in developing their information resource bases and obtaining information utilities from these resources; and further more by impoverished information assets to empower themselves in normal and problematic situations. Practical implications - Understanding of the information poor as sketched above will likely demand further research into a number of issues/areas hitherto ignored by information inequality studies. Originality/value - This paper is one of the first to address empirically one of the most fundamental questions in information inequality studies; it extends library and information science understanding of the information poor hitherto dominated by the information deficiency thesis.

    Abstract
    Purpose The purpose of this paper is to redefine information and other associated library and information science (LIS) concepts and to reformulate the mission of the library and information profession and the problem of LIS using these concepts. Design/methodology/approach his study adopts a deductive approach to conceptualization, starting from one given, a priori concept. Findings This paper develops a constellation of concepts which offer mutual clarification for each other. Having defined data by drawing on its existing denotations, it defines "information" as the combined product of data and meaning, and "document" as the combined product of information and media; it defines "knowledge" as one type of meaning and "work" as one type of information. It shows that the mission of the library and information profession is to ensure maximum discoverability and accessibility of information, and that LIS is structured into two fields correspondingly, each consisting of three tiers of knowledge: philosophical foundations, theories, and technologies. Practical implications The redefinition of basic LIS concepts may have practical implications for LIS curriculum design and for the cultivation of professional identity among LIS students in the all-encompassing I-Schools. Originality/value This study has formed a coherent conceptual framework for LIS and has clarified the hitherto rather confusing relationship between data, information, and knowledge, and the rather nebulous structure of LIS problems; it sheds some light on the source of conflicts between the subjective and objective conceptualization of information and questions the prevailing understanding of work as ideas or meanings.

    Abstract
    Purpose - Following the assumption that studies of information inequality need to be based on precise discrimination between society's information rich and poor and against the context that a mechanism for such discrimination is still lacking, the purpose of this paper is to explore the possibility of establishing a holistic informational measurement. Design/methodology/approach - It does so by developing a measurement based on the conceptualization of the individual as an information agent and his/her information world as his/her characterization. The development procedure consists of four steps: operationalization of the theoretical constructs and the initial drafting of the questionnaire instrument; revisions of the questionnaire based on pilot tests with small groups of people; weighing of the questionnaire items for the purpose of calculating index-type variable scores; formal test of validity and reliability. Findings - The resulting measurement consists of eight variables corresponding to eight theoretical constructs of an individual's information world, each being measured by a group of questionnaire-based items which, in turn, generate an index-type score as the variable's value. Validity and reliability tests show that the measurement is, on the whole, able to distinguish the information poor from the information rich and to measure individuals consistently. Originality/value - The study demonstrates that it is possible to distinguish the information rich and poor by informational measurement in the same way as to distinguish economic groups by income, ethnic groups by race and intelligence groups by IQ; and that such a measurement has arguably multifaceted value for information inequality research.

    Abstract
    Purpose Based on the assumption that information access disparity is a highly complex phenomenon demanding integrative explications that heed both structure and agency, the purpose of this paper is to outline the theoretical background against which endeavours to develop such explanations can be planned. Design/methodology/approach The study is based on a close reading of: existing explanations of information access disparity; research of other library and information science (LIS) issues that have demonstrated conscious attempts to bridge structure and agency; and cross-disciplinary integrative theories that have served as foundations for LIS research. Explanatory power of the first and applicability of the latter two are critically assessed; lessons for future research are drawn. Findings The examination shows that efforts to develop integrative theories for information access disparity are emerging but remain indistinct; integrative frameworks for other LIS phenomena exist but are developed primarily by adopting concepts from cross-disciplinary theories and are, therefore, both enabled and constrained by them. It also shows that cross-disciplinary integrative theories contribute to LIS by exporting the general integrative theorising approach and a range of specific concepts but, owing to their limitations in dealing with information-specific issues, their adequacy for explaining information access disparity cannot be assumed. Originality/value The study demonstrates that a promising way forward for developing integrative theories of information access disparity is to follow the general integrative approach, but to ground related concepts and propositions in empirical data alone, i.e., to begin the journey of integrative theorising theory-free.

    Abstract
    Purpose - The purpose of this paper is twofold: first, to investigate the epistemological underpinning of SERVQUAL and its limitations; and second, to propose ways to enhance the utility of SERVQUAL as a library assessment tool. Design/methodology/approach - The study first conceptualises quality judgment as a knowing process and locates the epistemological stance of SERVQUAL within the general framework of epistemology demarcation; it then examines related SERVQUAL assumptions and their implications for library assessment in general and for service quality assessment in particular based on two empirical investigations: a questionnaire survey and an interview survey. The questionnaire survey applies the SERVQUAL instrument to three Chinese university libraries, with a view to examining the SERVQUAL score in light of epistemological considerations; the interview survey interviews 50 faculty users in one of the three universities with a view to illuminating the naturalistic process through which users develop their judgement of the library's service quality and through which the SERVQUAL score is formed. Findings - The study shows that the actual SERVQUAL score is distributed in a very scattered manner in all three libraries, and that it is formed through a very complex process rooted primarily in the user's personal experiences with the library, which are in turn shaped by factors from both the library world and the user's life-world. Based on these findings, this research questions a number of SERVQUAL assumptions and proposes three concepts which may help to contextualise the SERVQUAL score and enhance its utility in actual library assessment: library planning based variance of user perception, perception-dependent user expectation and library-sophistication based user differentiation. Originality/value - The research presented in the paper questions a number of SERVQUAL assumptions and proposes three concepts that may help to contextualise the SERVQUAL score and enhance its utility in actual library assessment.
