    Abstract
    Reports results of 2 separate but related projects to study the influence of spelling errors (misspellings), made by searchers, on the subject searching of online catalogues and to suggest ways of improving error detection systems to handle the errors that they detect. This involved the categorization of user queries for subjects that were extracted from the online catalogue transaction logs of 4 USA university libraries. The research questions considered: the prevalence of misspellings in user queries for subjects; and how users respond to online catalogues that detect possible spelling errors in their subject queries. Less than 6% of user queries that match the catalogue's controlled and free text terms were found to contain spelling errors. While the majority of users corrected misspelled query words, a sizable proportion made an action that was even more detrimental than the original misspelling. Concludes with 3 recommended improvements: online catalogues should be equipped with search trees to place the burden of selecting a subject the system instead of the user; systems should be equipped with automatic spelling checking routines that inform users of possibly misspelled words; and online catalogues should be enhanced with tools and techniques to distinguish between queries that fail due to misspellings and correction failures. Cautions that spelling is not a serious problem but can seriously hinder the most routine subject search

    Abstract
    Popular commercial on-line services such as Google, e-Bay, Amazon, and Netflix have evolved quickly over the last decade to help people find what they want, developing information retrieval strategies such as usefully ranked results, spelling correction, and recommender systems. Online library catalogs (OPACs), in contrast, have changed little and are notoriously difficult for patrons to use (University of California Libraries, 2005). Over the past year (June 2005 to the present), the Melvyl Recommender Project (California Digital Library, 2005) has been exploring methods and feasibility of closing the gap between features that library patrons want and have come to expect from information retrieval systems and what libraries are currently equipped to deliver. The project team conducted exploratory work in five topic areas: relevance ranking, auto-correction, use of a text-based discovery system, user interface strategies, and recommending. This article focuses specifically on the recommending portion of the project and potential extensions to that work.

    Abstract
    There is currently a lively debate about the role of the library catalogue and its relationship to other resource discovery tools. An example of this debate is the recent publication of a report commissioned by the Library of Congress on "the changing nature of the catalogue" As part of this debate, the role of union catalogues is also being re-examined. Some commentators have suggested that union catalogues, by virtue of their size, can aggregate both supply and demand, thus increasing the chance that a relatively little-used resource will be discovered by somebody for whom it is relevant. During the past year, the National Library of Australia (NLA) has been considering the future of its catalogue and its role in the resource discovery and delivery process. The review was prompted, in part, by the redevelopment of the Australian union catalogue and its exposure on the web as a free public service, badged as Libraries Australia. The NLA examined the enablers and inhibitors to proposition "that it replace its catalogue with Libraries Australia, as the primary database to be searched by users". Flowing from this review, the NLA is aiming to undertake a number of tasks to move in the medium to long term towards a scenario in which it could deprecate its local catalogue.
