Considering the importance of subject retrieval for scientific visibility, and the need to guide authors in self-archiving their papers in institutional repositories of university libraries, this study observed the patterns and strategies used by authors while indexing for keyword assignment. The study examined four categories of analysis: criteria for keyword assignment; use of controlled vocabulary for keyword assignment; understanding of the importance of keywords; and ordering criteria and function of assigned keywords. The study found that, while assigning keywords, authors: consider fundamental concepts for representing significant content of the text; act as domain expert indexers; and are unaware that keyword assignment is an indexing process that requires controlled vocabularies. The research suggests that institutional repositories implement a hybrid information representation and retrieval system to allow for both the representation of more specific subjects of knowledge domains, as well as controlled vocabulary indexing terms.

Subject indexing is responsible for representing the content of information resources in a way that can be retrieved by users in an information system. This paper presents the importance of indexing in the process of search engine ranking and aims to verify how the elements of the theory and practice of indexing can contribute to information retrieval. The research seeks to identify if Search Engine Optimization techniques have proximity with the elements of subject indexing. Considering the lack of investigations dedicated to the dialog between the two themes, a literature review was used as methodology, in order to contextualize the current research scenario on both themes. The results indicate few works that address the themes of Search Engine Optimization and indexing, together. It is concluded that there is an integration between indexing practices and Search Engine Optimization techniques, describing which elements of indexing can collaborate to search engine ranking.

The metadata of theses and dissertations are inserted in the repositories automatically or manually, in Dublin Core format, different from the one used by the libraries, generating duplicity of work. The objective is to compare the procedures of thematic treatment of theses and dissertations existing in the online catalogue and in the repository, through the analysis of subject metadata. An exploratory study was carried out with a case study on the use of vocabulary control in theses and dissertations metadata, with the institutional repository of São Paulo State University and the Athena online catalog of the same institution. The exploratory study had two stages: documentary study of the historical trajectory of treatment of theses and dissertations at university and analysis of procedures of thematic treatment of theses and dissertations in databases, by authors and catalogers. The analysis of thematic treatment procedures employed observation of functioning and of routines and patterns, for evaluation of vocabulary control in the analysis of subject metadata. The results obtained revealed that the vocabulary control is not done in the search interfaces for information retrieval and neither in the alphabetical list of keywords, which means lack of guidance to authors, regarding the assignment of descriptors. The analyses showed two thematic treatments, which results in different subject representations, in natural language, in the repository, and in controlled language, in the catalogue. Two proposals were elaborated for the thematic treatment in subject metadata of theses and dissertations in repositories and library catalogues. It is concluded that the proposals may be assisted by the elaboration of an indexing policy of the repository that foresees the sharing of data resulting from self-archiving of theses and dissertations with the catalogue and that can accept the attribution of controlled vocabulary descriptors, besides the attribution of keywords.

This work aims at evaluating the indexing of subject metadata published on the MercadoEditorial.org platform. The goal: to verify if the indexing is consistent. First, analysis was done of the tools available on the platform for assigning keywords, and, afterwards, publishers on the platform were documented and verified by running intrinsic evaluation for interconsistency. This was all done to compare the indexing of one work by four authors. The authors were Ciranda Cultural, IBEP, Excelsior Editora, and Via Leitura. The chosen book was "The Alienist" by Machado de Assis, a classic in Brazilian literature. The result of the indexing analysis was that publishers gave keywords such as title, author's name, characters' names, names of other books, and excessively used and repeated words. The last category was further broken down being with or without accentuation, being in the singular or plural form. Other terms were assigned that were related to university entrance exams. Thus, it can be concluded that an absence of vocabulary control can make retrieval of a work difficult, simply by assigning terms that inadequately define the subject of the book, and by lacking semantic, syntactic, and morphological standardization among the terms.

Introduction: Vocabulary control in information resource storage, treatment and retrieval systems is necessary to obtain consistency between indexing and retrieval in order to avoid informational dispersion. Digital repositories in universities are currently fundamental in the organization and management of knowledge generated by scientific, technological, artistic, and administrative production, however, it is necessary to verify the availability of controlled vocabulary and how vocabulary control is carried out. Objective: With the objective of systematizing a proposal for vocabulary control and the use of controlled vocabularies in university repositories managed by libraries, an evaluation model was developed that proposes to systematize methods, procedures, resources, and techniques. Methodology: For this, the development of the investigation carried out exploratory research with bibliographic and documentary research and applied research in the Unesp Repository. Results: The results obtained constituted an Action Plan, discussed and elaborated by the Study Group, composed of six actions and nine studies to evaluate and control vocabulary in university repositories about: vocabulary control in indexing by professionals and non-professionals; vocabulary control in retrieval; use of subject metadata from academic papers; keyword matching; analysis of terminological variations at semantic, syntactic and pragmatic levels; analysis of transaction logs for searches by subject. Conclusion: It is concluded that the systematization of actions in an evaluation model is relevant for university repositories to incorporate the advances offered by vocabulary control in their routines and, mainly, for the contribution of new terms arising from scientific and technological evolution.

The massive and unstoppable emergence of electronic books in libraries has altered their organization. This disruptive technology has led to structural changes. Currently, an e-book exists only if its metadata exists. The objective of this article is to analyse the impact that the massive incorporation of electronic books in university library systems is having in the processes of assignment of subject headings and classification codes. We carried out a survey of more than six hundred libraries, which means almost all the university libraries in Portugal, Spain, England, United States, Brazil, Sweden, Norway, Finland and Australia. From the results obtained, it is deduced that: 1) librarians expect ebooks to be provided with descriptive metadata related to the subject headings and classification codes; 2) the bibliographic records provided by publishers/providers seem to be improvable; 3) the quality of the metadata provided by the providers does not seem to be taken into account when selecting publishers for the purchase; 4) the discovery tools are also clearly improvable; 5) it seems that there is no "frustration" or "stress" among librarians about the changes produced in relation to technical processes; and, 6) it does not seem that we are facing a paradigm shift motivated by these issues.

The construction and updating of indexing languages depend on the organization of their hierarchical structures in order to determine the classification of related terms and, above all, to allow a constant updating of vocabulary, a condition for knowledge evolution. The elaboration of an indexing language for online catalogs of libraries' networks is important considering the diversity and specificity of knowledge areas. From this perspective, the present paper reports on the work of a team of catalogers and researchers engaged in the construction of a hierarchical structure of an indexing language for an online catalog of a university library's network. The work on hierarchical structures began by defining the categories and subcategories that form the indexing language macrostructure by using the parameters of the Library of Congress Subject Headings, the National Library Terminology and the Vocabulary of the University of São Paulo Library's system. Throughout the stages of the elaboration process of the macrostructure, difficulties and improvements were observed and discussed. The results enabled the assessment of the hierarchical structures of the languages used in the organization of the superordinate and subordinate terms, which has contributed to the systematization of operational procedures contained in an indexing language manual for online catalogs of libraries.
