    Abstract
    Terms chosen to represent document subjects, the classification notations assigned to them, the abstracts and indices contain biases in two contexts. In a negative context, document surrogates are constructed with bias when they leave out diverse features, disenfranchise groups and topics outside an accepted norm (Olson, 2002). In this way, these document surrogates would convey inclinations, or prejudices. In a positive context, slanting or tendency (Hjørland, 2008a, McIlwaine, 2003) conveyed by the document surrogates to ensure specificity to particular discursive communities or knowledge domains can be observed. Considering that topics related to biases are scarce in the Information Organization literature, this paper proposes a discussion on the characteristics and occurrences of bias in subject representation. This study is exploratory and bibliographic, and adopts an inductive method.

    Abstract
    After two decades in the 21st Century, and despite all the advances in the area, some very important names from past centuries still do not have the recognition they deserve in the global history of library and information science and, specifically, of knowledge organization. Although acknowledged in British librarianship, the name of James Duff Brown (1862-1914) still does not have a proper recognition on a global scale. His contributions to a free and more democratic library had a prominent place in the works and projects he developed during his time at the libraries of Clerkenwell and Islington in London. Free access to the library shelves, an architecture centered on books and people, and classifications that are more dynamic were dreams fulfilled by Brown. With this biographical article, we hope to live up to his legacy and pay homage to a true librarian and an advocate of the public library and subject classification.

    Abstract
    This paper aims to study the conceptual dimension of Knowledge Organization (KO) in the ISKO proceedings (1990-2012) domain. After analyzing a corpus of 71 papers that presented the term "knowledge organization" in their titles, using the methodology of Bardin's content analysis, it was possible to obtain a set of 11 definitions of KO which were studied using the following categories: nature, object, tools, processes, and perspectives/approaches. These categories act as a basis to identify the communities of authors that interact in the domain under different conceptual perspectives. The results show that KO has been mainly understood as an area or field of knowledge whose objects are recorded knowledge and conceptual structures, and whose main processes are classification and indexing, as well as information retrieval. The nature of KO is mostly linked to the construction of specialized discourses and the methodological dimension of such area is related to the systematization of recorded scientific knowledge.

    Abstract
    This paper arises from the possibility of a theoretical dialogue between the socio-cognitive perspectives of knowledge organization and the Bakhtinian concepts on conscience, "responsible act," "responsive understanding," and polyphony as attitudes that motivate the dialogism that is inherent to language. Those questions allow us to recognize the professional that organizes and represents knowledge as someone who has an intersubjective conscience, a product composed by two axes that are indeed deeply connected: the "self " and the "other." Therefore, the acts of representing and organizing knowledge are deeply affected by external discourses and by internal discourses. Those different discourses come together at the moment of representing the knowledge and act as a response to the dialogues between the external and the internal discourses. As a consequence, the indexing/ classification codes, terms or signs assume a dialogical and dynamic representativeness in order to correspond not only to the contents of the documents but also to dialogue with a diverse user community, by the recognition of the alterity/otherness of the social actors and the social situations. Finally, it is important to point out the need of an ethical and democratic attitude of the indexer/classifier, in order to represent the social pluralism and show an equipollence of social voices.

    Abstract
    Personal data play a fundamental role in contemporary socioeconomic dynamics, with one of its primary aspects being the potential to facilitate discriminatory situations. This situation impacts the knowledge organization field especially because it considers personal data as elements (facets) to categorize persons under an economic and sometimes discriminatory perspective. The research corpus was collected at Scopus and Web of Science until the end of 2021, under the terms "data discrimination", "algorithmic bias", "algorithmic discrimination" and "fair algorithms". The obtained results allowed to infer that the analyzed knowledge domain predominantly incorporates personal data, whether in its behavioral dimension or in the scope of the so-called sensitive data. These data are susceptible to the action of algorithms of different orders, such as relevance, filtering, predictive, social ranking, content recommendation and random classification. Such algorithms can have discriminatory biases in their programming related to gender, sexual orientation, race, nationality, religion, age, social class, socioeconomic profile, physical appearance, and political positioning.

    Abstract
    Aiming at contributing to the epistemological characterization of the area of knowledge organization, our goal is to analyze the KO journal, since its creation in 1993, as a knowledge domain, from a nuclear community of the most productive and greater impact authors, analyzing the dialogue among citing authors and cited ones, and also the co-citations established by the citing authors. We worked with a corpus of 310 articles published between 1993 and 2011 produced by a total of 360 authors. The relatively more productive authors, a group geographically concentrated in Europe (37%), North America (44%) and Asia (19%), is clearly explained by the historical European origin of the ISKO and by an increasing North American presence along the years. Of the 33 most cited authors, 22 were co-cited in at least 6 works, which suggests that they are the theoretical referential nucleus of the area, in the studied journal. Finally, we observe that the area reveals theme cohesion and coherence in its production, enabling us to clearly visualize its theoretical referential nucleus and to confirm the role performed by the KO magazine as a catalyzing agent of international theoretical construction in the area.
