The bacterial plant pathogen Pseudomonas syringae pv. phaseolicola (Pph) colonises the surface of common bean plants before moving into the interior of plant tissue, via wounds and stomata. In the intercellular spaces the pathogen proliferates in the apoplastic fluid and forms microcolonies (biofilms) around plant cells. If the pathogen can suppress the plant’s natural resistance response, it will cause halo blight disease. The process of resistance suppression is fairly well understood, but the mechanisms used by the pathogen in colonisation are less clear. We hypothesised that we could apply in vitro genetic screens to look for changes in motility, colony formation, and adhesion, which are proxies for infection, microcolony formation and cell adhesion. We made transposon (Tn) mutant libraries of Pph strains 1448A and 1302A and found 106/1920 mutants exhibited alterations in colony morphology, motility and biofilm formation. Identification of the insertion point of the Tn identified within the genome highlighted, as expected, a number of altered motility mutants bearing mutations in genes encoding various parts of the flagellum. Genes involved in nutrient biosynthesis, membrane associated proteins, and a number of conserved hypothetical protein (CHP) genes were also identified. A mutation of one CHP gene caused a positive increase in in planta bacterial growth. This rapid and inexpensive screening method allows the discovery of genes important for in vitro traits that can be correlated to roles in the plant interaction

In 1957, John Sperry Jr. published an article in Libri entitled “Egyptian libraries: a survey of the evidence.” Some 55 years on, this article revisits the subject, taking into account research undertaken in the field of Egyptology over the last half a century. Based on an extended essay written for the online Certificate in Egyptology course at the University of Manchester, this article considers the evidence for the existence of “institutional” (that is, created for the use and functioning of the state) libraries and archives in Ancient Egypt throughout the dynastic period (c.3500−30 B.C.); their history, purpose and, to some extent, their administration. It also considers an aspect not explored in Sperry’s article, that of “private” libraries in Ancient Egypt (texts collected by an individual for their own personal use). Whilst estimated literacy levels within the general population precluded the widespread collection of texts for personal edification, there is evidence to suggest that private libraries were present in Ancient Egypt. The article concludes with a brief assessment of the legacy of these ancient libraries and their influence on the creation of the Library of Alexandria, in both its ancient and modern manifestations.

Libraries are very propitious environments for the growth of fungi. The great concentration of organic material available for these microorganisms, and often with the lack of adequate ventilation or climate control, would favour this situation. This study was conducted in 2003 to determine the predominant genera of fungi in public libraries by a survey of fungi contaminating the upper surface of books, with and without air conditioning in the city of Sao Paulo, Brazil, in the winter and summer, during the respective periods with high and low levels of airborne fungi in that city. Six libraries were chosen, located on the campus of the University of Sao Paulo, three of them with air conditioning and the other three with natural ventilation. In these six libraries, 31 genera of fungi were identified in total. The genera and frequency of contaminant fungi recovered differed significantly between the libraries with and without air conditioning and in the samples collected in the summer as opposed to the winter. Cladosporium was the most frequent in the libraries with and without air conditioning, and in the winter. Aspergillus was isolated more often in the summer.

One of the major challenges of university libraries is to adequately support the information needs of researchers. This paper outlines the results of a survey conducted by Deakin University Library into the information needs of researchers and the library’s perceived role and performance. The survey consisted of twenty-three interviews conducted with researchers, and its results challenged established ideas regarding researchers’ preference for print, age of resources required, and reliance on specialist rather than general or cross-disciplinary databases. Of note were the decreasing physical use of the library, the increasing importance of online resources and the changing need for library support services. The study raises some key questions relating to the future of libraries and the role of librarians.

Findings from informetric research represent an important background resource to add to the mix of information useful for resolving difficult and ongoing problems in specific library environments or information service settings. This paper provides examples of informetric research that can be useful input to decision-making in the field of library management and information service provision. This overview takes four of the challenges that Michael Buckland outlined for library research as a way of guiding the discussion of ways that informetric work can be used to inform library decision-making. (1) References are made to relevant informetric work undertaken or conducted in Australia, by Australian researchers, or with Australian data.
Informetrics includes both quantitative and qualitative methods, which when used in combination can provide a rounded set of findings that has great validity for management, policy and service applications. Quantitative methodologies are generally based on bibliometric techniques, such as mining and analysis of data from various bibliographic and textual databases. Qualitative methods include survey, case study and historical approaches. Used in combination, each set of findings adds richness and other perspectives to an analysis.

This thesis analyses the development of the Ballarat East Free Library (1859), the Ballarat Mechanics’ Institute Library (1859) and the City of Ballaarat Free Library (1878) within the broader context of public librarianship in Victoria between 1851-1900. Mechanics’ Institute libraries and free libraries represent the major derivatives of a nineteenth-century library model that emphasised the pursuit of lifelong learning, private reading and the enjoyment of genteel recreational facilities. The circumstances that led to the formation of an Institute and a free library in Ballarat in, 1,859 provide a unique opportunity to analyse the public library model for two reasons. These libraries were established in a remarkable goldfield city that enjoyed a number of economic and cultural advantages and secondly, the Ballarat Mechanics’ Institute Library and the Ballarat East Free Library experienced such spectacular growth that by 1880 they were two of the largest public libraries in Australia. However, it is argued that this growth cycle could not be sustained due to a combination of factors including low membership levels, limited funding for recurrent expenditure purposes, and heightened dissatisfaction with the book collections. Libraries began to stagnate in the late-1880s and the magnitude of this collapse in Ballarat, and throughout the colony, was subsequently confirmed with the publication of a national survey of Australian libraries in 1935. The ‘Munn-Pitt’ report found that public libraries had provided a better service in 1880 than at any other time in the next six decades. Four conclusions are drawn in this comparative analysis of the Ballarat Mechanics’ Institute Library, the Ballarat East Free Library, and to a lesser extent, the City of Ballaarat Free Library, between 1851-1900. Firstly, is it shown that the literature places considerable emphasis on the formation of public libraries but is far less critical of the long-term viability of the public library model as it evolved in Ballarat and throughout the colony in the nineteenth century. Secondly, whilst Ballarat and its library committees benefited from the city's prosperity and the entrepreneurial zeal of its pioneers, these same library committees were unable to overcome the structural flaws in the public library model or to dispel the widespread belief that libraries were elitist organisations. As a consequence, membership of the major libraries in Ballarat never exceeded 4% of the total population. Thirdly, it is acknowledged that an absence of records relating to book borrowing habits by individuals limits is a limiting factor, but this problem has been addressed, in part, by undertaking a comparative analysis of collection development policies, invoices, lists of popular authors and books, public comment and the book borrowing patterns of a number of comparable libraries in central Victoria. These resources provide a number of insights into the reading habits of library patrons in Ballarat in the late-nineteenth century. Finally, this thesis focuses on the management policies and practices of each library committee in Ballarat in order to move beyond the traditional explanation for the demise of nineteenth-century libraries and to propose an alternative explanation for the stagnation of public libraries in Ballarat in the mid-1880s. The traditional explanation for the demise of colonial libraries was the sudden reduction in government funding in the 1890s, whereas this thesis argues that a combination of factors, including the unresolved tensions with regard to libraries collection development policies, committee and municipal rivalry, and increasing conservatism, had already damaged the credibility of Ballarat’s libraries by the mid-1880s. It is argued that the intense rivalry between library committees resulted in an unnecessary duplication of services and an inadequate membership base. It is also argued that the increasingly conservative, un-cooperative and uninviting attitudes of these library committees discouraged patronage and as a direct consequence, membership and daily visitor rates of the free and Institute libraries in Ballarat plummeted by 80% between 1880-1900.

Academic libraries are taken to refer here to two particular types of library: university libraries and those libraries which serve the vocational education and training (VET) sector through colleges or institutes of technical and further education (TAFE). (School libraries are dealt with in a separate chapter.) Universities cover undergraduate programs, principally Bachelors degrees, and postgraduate programs such as the Graduate Certificate, Graduate Diploma, Masters degrees and doctoral programs. The main TAFE awards are Certificate, Diploma and Advanced Diploma. Universities are largely funded by national government - the federal Commonwealth Government in Australia's case - although, as elsewhere, an increasing amount of university funding needs to come from non-government sources, particularly research funding. In Australia institutes of TAFE are funded by state and territory governments, although from 2005 the Federal Government began providing funding for the development of technical colleges outside the TAFE sector that would provide vocational education for secondary school age students. This latter development may well be affected by the change in federal government in late 2007.
The mission for academic libraries globally is to support the teaching, learning and (where appropriate) research activities of their parent institutions. In Australia and New Zealand, universities and their libraries have also had a long tradition of reaching out to the community, contributing to the cultural and intellectual life of the nation. Australia has thirty-nine universities; of which thirty-seven are public institutions and two are private. New Zealand has eight universities. The libraries supporting these institutions are diverse, of high quality and innovative. Based on 2005 figures, there are sixty-eight institutions in Australia's VET sector, with over 1,100 campuses, 1.7 million students and some eleven per cent of Australia's working age population accessing TAPE (Oakley & Vaugha 2007: 43).

In Australia and New Zealand, the term 'special library' refers to libraries that provide resources and services to employees of an organization or industry. The majority have collections and/or services supporting a specific subject area. These include, but are not limited to, libraries in government department, law firms, private companies, banking and finance institutions, research organizations, religious groups and professional associations.
