- Abstract
- Mbooks are open-access, digitized books freely available on the Internet. This article describes the Auraria Library's experience of loading brief MARC records for Mbooks into its online public access catalog and looks at some of the issues that arose from the record-loading project. Despite the low quality of the records, librarians in Auraria Library thought that loading them into the catalog was advantageous because of the rich content in the collection and because many of the records could be improved using the global update functionality in the catalog. Making the records available through the catalog, as opposed to merely linking to the entire collection from the Library's web page, was considered to be valuable because of the aggregation a catalog provides and because the Mbooks collection helped fill gaps in the Library's physical collections. As more open-access, digitized books become available, libraries will need to plan and manage how best to provide access to them.

- Abstract
- Magda Heiner-Freiling argued for assignment of extra DDC numbers for improved access, including table numbers and other parts of numbers as well as fully built numbers, and for coding to identify component parts of built numbers. Changes to the MARC 21 Bibliographic format that support her approach are found in MARC Proposal No. 2008-01 Representation of the Dewey Decimal Classification (DDC) System in MARC 21 formats. The new 083 Additional Dewey Decimal Classification Number field is used for assignment of extra Dewey numbers for improved access. The new 085 Synthesized Classification Number Components field is used to identify component parts of built Dewey numbers. This paper uses specific examples to show how the new fields can help improve access.

- Abstract
- Typographical errors can block access to records in online catalogs; but, when a word contains a typo and is also spelled correctly elsewhere in the same record, access may not be blocked. To quantify the effect of typographical errors in records on information retrieval, we conducted a study to measure the proportion of records that contain a typographical error but that do not also contain a correct spelling of the same word. This article presents the experimental design, results of the study, and a statistical analysis of the results.We find that the average proportion of records that are blocked by the presence of a typo (that is, records in which a correct spelling of the word does not also occur) ranges from 35% to 99%, depending upon the frequency of the word being searched and the likelihood of the word being misspelled.

- Abstract
- Catalogers at Harvard University have been adding form and genre data to MARC records in HOLLIS, the University's online library catalog, since 1994. The addition of this data in bibliographic records allows library users to more easily access some materials described in the catalog. This paper describes how form and genre data is indexed in the catalog and analyzes the value of adding, indexing, and using this bibliographic data.

- Abstract
- Dewey for Windows (DFW) provides a Windows interface for the Dewey Decimal Classification (DDC). The DFW interface is different from the DOS version of Electronic Dewey, but the search engine (database access program) is similar . This paper does not attempt to survey all the features of DFW; it focuses on those features that seem most important to the working classifier. It describes the hierarchies and the extra terminology for searching added to the DDC 21 database, search strategies, the limited number of built numbers in the database, and the need for number building. This paper also includes detailed descriptions of sample searches that illustrate how the system works.
