Modern Image

The modern image library, with its large collections in a multiplicity of formats, requires sophisticated systems of classification, indexing and information retrieval. Alongside the traditional art historical approach to the reproductions it contains, iconographic indexes are being developed which treat art as a language and analyse signs, symbols and meanings. Given the increase in iconographic and iconological research there is a need for the co-ordination and standardisation of indexing techniques at an international level.

Evidencia a ausência de interdisciplinaridade entre a Biblioteconomia e Tecnologia da Informação (TI), no que tange tratamento de acervos digitais e híbridos, bem como a necessidade da participação do bibliotecário em projetos de softwares livres para bibliotecas. Aponta as mazelas relacionadas à aquisição de softwares proprietários pelas bibliotecas. Defende a redefinição de metodologias acerca das técnicas de indexação e a necessidade da ruptura contemplativa na postura do bibliotecário; o que agilizaria e modificaria processos, contribuindo na tomada de decisão em busca do tratamento e da qualidade na disseminação e recuperação da informação. Palavras-chave: Biblioteconomia; Tecnologia da Informação; Gerenciamento da Informação; Softwares para bibliotecas; Bibliotecários - Postura Abstract It evidences the interdisciplinary lack between the Librarianship and Information Technology regarding, in what it plays treatment of digital and hybrid collections, as well as the need of the librarian's participation in projects of free softwares for libraries – it points out on the sore spots related to the softwares proprietors' acquisition for the libraries. It defends the redefinition of methodologies concerning the indexing techniques and the need of the thoughtful rupture in the librarian's posture; what would activate and modify processes, contributing to the decision making in search of the treatment and quality in the dissemination information retrieval.

Pilar Wyman reports on the work of the US National Information Standards Organization (NISO) Criteria for Indexes project, which aims to revise and extend the NISO TR02-1997 Guidelines for indexes and related information retrieval devices. The guidelines have not been reviewed since 1984 and will thus be updated to address modern indexing techniques.

Continuous Record

We have long felt that some form of electronic information retrieval would be more desirable than conventional photographic methods in a high vacuum electron microscope for various reasons. The most obvious of these is the fact that with electronic data retrieval the major source of gas load is removed from the instrument. An equally important reason is that if any subsequent analysis of the data is to be made, a continuous record on magnetic tape gives a much larger quantity of data and gives it in a form far more satisfactory for subsequent processing.

Contrast Information

Many factors (e.g., resolution of microscope, type of tissue, and preparation of sample) affect electron microscopical images and alter the amount of information that can be retrieved from a specimen. Of interest in this report are those factors associated with the evaluation of epoxy embedded tissues. In this context, informational retrieval is dependant, in part, on the ability to “see” sample detail (e.g., contrast) and, in part, on tue quality of sample preservation. Two aspects of this problem will be discussed: 1) epoxy resins and their effect on image contrast, information retrieval, and sample preservation; and 2) the interaction between some stains commonly used for enhancing contrast and information retrieval.
