Abstract

This article defines and outlines the characteristics of map series, map sets, map serials, maps in multiple editions and multi-sheet single maps. Brief instructions on sources of information and general methodology used in gathering information prior to creating the entry are presented. The different methods which may be used for cataloguing series and serials are explored. There is also a brief section on cataloguing bi- and multi-lingual works in a bilingual environment. For each relevant area of description, instructions and examples are given to illustrate problems. Sections on analysis (including multi-level cataloguing).

Content

We have all heard the story of the three blind men who were put next to an elephant and asked to describe it. Each of them touched a different part of the beast, and because none of them could examine the entire creature, their resulting description was neither accurate nor useful. Constructing a catalog has always been a bit like describing elephants blind, and rather than getting easier as standardization and new technologies are widely implemented, the emergence of new types of information resources are making the job more difficult. Remotely-accessible electronic information resources are among the newest of cataloging's elephants. Not only is it difficult to see -or touch the entire animal, but the creature may move or change during or after the description process. The beast is also unwieldy, and the person doing the description may have no control or ownership of it. The temptation is great to say that it is not our business to describe either this particular beast or any other animal that we don't own, and to walk away. Unfortunately, remotely-accessible electronic information resources are increasing in number and importance, and access to information about materials over which the local library has no control is becoming both easier and more common. Library users more and more expect to have access to these resources, so the option of leaving them undescribed and thus excluding them from the catalog is becoming indefensible. In coming to grips with the problem of describing these exotic beasts, it may be helpful to recall how we have dealt with similar challenges in the past, and to remember that the practices, rules, policies, and principles that surround and define the activity of cataloging have always reflected the current concept of what constitutes a library catalog, and that that concept inevitably reflects both the history and role of libraries and available technology. Until relatively recently the primary roles of a catalog were widely recognized to be providing inventory control for a particular collection and serving as a finding aid to that collection only, but in practice, even the most elaborate catalogs never fulfilled even these roles entirely. Whole categories of materials, such as maps, photographs, newspapers, pamphlets, and rare books were excluded, or at best were described in separate catalogs or finding aids. Information about the contents of individual objects, such as chapters, contributions, and journal articles were also rarely included in the catalog. A small number of major parts of some works were described through analytic cataloging, and contents of other items were sometimes listed in notes in cataloging records when those parts were considered separable and potentially important in their own right, but because entries were generally not made for items included in contents notes the lists were primarily useful to those who had already found the main record. Description of the internal contents of information resources was left to reference works such as indexes and bibliographies. Far from being viewed as a flaw or insufficiency in the catalog, this need to use outside finding aids was accepted as the way things were.

Abstract

In order to test how associated verbal and spatial stimuli are processed in memory, undergraduates studied a reference map as either an intact unit or as a series of individual features, and read a text containing facts related to map features. In Addition, the map was presented either before or after reading the text. Seeing the intact map prior to the text led to better recall of both map information and facts from the text. These results support a dual coding modell, where stimuli such as maps possess a retrieval advantage because they allow simultaneous representation in working memory. This advantage occurs because information from the map can be used to cue retrieval of associated verbal facts, without exceeding the processing constraints of the memorial system

Abstract

This article identifies the types of publications containing maps and the need for access to maps contained in them. The emphasis is on older maps; the comments are opposite for cataloging of current maps. The needs of map users are discussed, identifying the points of access that are critical to successful map retrieval. Main entry for maps is discussed. Various categories of associated map and book items are identified, and suggestions made, with USMARC examples, as to how these maps might be treated by the cataloger

Abstract

To improve searching, filtering and processing of information on the Web, a common effort is made in the direction of metadata, defined as machine understandable information about Web resources or other things. In particular, the eXtensible Markup Language (XML) aims at providing a common syntax to emerging metadata formats. Proposes the Structured Graph Format (SGF) an XML compliant markup language based on structured graphs, for capturing Web sites' structure. Presents SGMapper, a client-site tool, which aims to facilitate navigation in large Web sites by generating highly interactive site maps using SGF metadata

Abstract

Maps have bibliographic characteristics which present unusual challenges to traditional cataloging practices. Rare maps carry these challenges even further by requiring bibliographic descriptions that identify and distinguish the item in hand from any other copies. While it has been acknowledged that rare maps should be bibliographically described in a different manner than modern maps, as rare printed texts are described in a differently than modern texts, the map cataloging community is uncertain about how this should be accomplished. This article attempts to identify some problems unique to the cataloging of rare maps. It also discusses the appropriateness of current map cataloging rules for rare maps and the importance of thorough cartobibliographic research.

Abstract

Forty-five years have passed since Lubetzky outlined the primary objectives of the catalog, which should facilitate the identification of specific bibliographic entities, and the explicit recoguition of works and relationships amongthem. Still, our catalogs are better designed to identify specific bibliographic entities than they are to guide users among the network of potential related editions and translations of works. In this paper, we seck to examine qualitatively some interesting examples of families of related works, defined as bibliographic families. Although the cases described here were derived from a random sample, this is a qualitative analysis. We selected these bibliographic families for their ability to reveal the strengths and weaknesses of Leazer's model, which incorporates relationship taxonomies by Tillett and Smiraglia Qualitatice analysis is intended to produce on explanation of a phenomenou, particularly an identification of any palterns observed. Patterns observed in qualitative analysis can be used to affirm external observations of the same phenomena; conclusions can contribute to what is knoton as grounded theory-a unique explanation grounded in the phenomenon under study. We arrive at two statements of grounded theory concerning bibliographic families: cataloger-generated implicit maps among works are inadequate, and qualitative analysis suggests the complexity of even the smallest bibliographic families. We conclude that user behavior study is needed to suggest which alternative maps are preferable.

Abstract

Discusses the nature and purpose of cartobibliography; the study of bibliography as applied specifically to maps. Maps, although bibliographically and physically awkward, present valuable information in much more concentrated form than books. Cartobibliographies, reflecting the complexity of maps, come in many varieties, depending on the purposes and rationales behind them

Abstract

Part 1 of a series of articles, exploring the concept of 'the work' in cataloguing practice, which attempts to construct a definition of the term based on AACR theory and practice. The study begins with a consideration of the objects of the catalogue, their history and the evidence that bears on the question of the degree to which the user needs access to the work, as opposed to a particular edition of the work

Abstract

We present a declarative language for the construction of hypertext views on databases. The language is based on an object-oriented data model and a simple hypertext model with reference and inclusion links. A hypertext view specification consists in a collection of parameterized node schemes which specify how to construct node and links instances from the database contents. We show how this language can express different issues in hypertext view design. These include: the direct mapping of objects to nodes; the construction of complex nodes based on sets of objects; the representation of polymorphic sets of objects; and the representation of tree and graph structures. We have defined sublanguages corresponding to particular database models (relational, semantic, object-oriented) and implemented tools to generate Web views for these database models

Abstract

Interactive dynamic maps (IDMs) help users interactively explore webs of hypermedia documents. IDMs provide automatically generated abstract graphical views at different levels of granularity. Visual cues give users a better understanding of the content of the web, which results in better navigation control and more accurate and effective expressions of queries. IDMs consist of: topic maps, which provide visual abstractions of the semantic content of a web documents and document maps, which provide visual abstractions of subsets of documents. The major contribution of this work include: automatique techniques for building maps directly from a web of documents, including extraction of semantic content and use of a spatial metaphor for generating layout and filing space, a direct manipulation interaction paradigm for exploring webs of documents, using maps and an integrated graphical query language, and the ability to use the maps themselves as documents that can be customized, stored in a library and shared among users
