    Abstract
    Purpose - This study aims to consider the value of user-assigned image tags by comparing the facets that are represented in image tags with those that are present in image queries to see if there is a similarity in the way that users describe and search for images. Design/methodology/approach - A sample dataset was created by downloading a selection of images and associated tags from Flickr, the online photo-sharing web site. The tags were categorised using image facets from Shatford's matrix, which has been widely used in previous research into image indexing and retrieval. The facets present in the image tags were then compared with the results of previous research into image queries. Findings - The results reveal that there are broad similarities between the facets present in image tags and queries, with people and objects being the most common facet, followed by location. However, the results also show that there are differences in the level of specificity between tags and queries, with image tags containing more generic terms and image queries consisting of more specific terms. The study concludes that users do describe and search for images using similar image facets, but that measures to close the gap between specific queries and generic tags would improve the value of user tags in indexing image collections. Originality/value - Research into tagging has tended to focus on textual resources with less research into non-textual documents. In particular, little research has been undertaken into how user tags compare to the terms used in search queries, particularly in the context of digital images.

    Abstract
    Following from approaches that view information as documentary forms of specific communicative practices, this paper uses theoretical concepts derived from cultural theory to examine the concept of work in Functional Requirements for Bibliographic Records (FRBR) in relation to authorship, the ur-text, and intertextuality. Historically, the practice of librarianship has existed on a foundation of standards, and among the earliest of the standards is the Anglo-American Cataloguing Rules (AACR). The basis of this set of standards is materialist: the object of scrutiny is the document, and the document, whatever its specific form, is considered to possess materiality. This paper argues that unlike the AACR, FRBR lays bare its own ideological underpinnings, and in so doing, it dematerializes the text and mystifies the creative process. At the same time, it has really been with the development of FRBR and linked-data models that library and information science has considered intertextual analysis at the level of the document rather than at a more abstract level. The idealism that underpins FRBR's notion of work points to intertextuality, with all its potential for rich analysis, but at the same time embeds deep in its system the logocentrism of the ideal signified-another example of disciplining epistemology. The paper will examine these two interlinked themes through discussion of FRBR and the strange case of the vanishing text, the ur-text, and intertextuality.
