Modern libraries have as their main mission the provision of equal access to information and their services. At the same time, it is a constituent part of the social fabric, which contributes to the democratization of society, personal development and social progress. Therefore, information professionals should seek to cultivate a culture that promotes equality, inclusion and diversity to achieve the aforementioned goals.

The present study aspires on the one hand, to highlight the policies, practices, services and collections, that are developed to support people with diversity in terms of sexual orientation, gender expression and identity and on the other hand, to highlight the perceptions of Greek librarians, regarding the information needs of the community in question and the factors influencing them.

This is a modern exploratory type study, as a problem is formulated, which in this case is the policies of libraries and the perceptions of librarians, with the ultimate goal of making observations on a specific sample, coming from a wider population at a given time, by conducting the research. The questionnaire addressed to librarians of Greek public and academic libraries will be used as the research instrument.

The key questions that this study will focus on are whether libraries provide, as they should, free and unimpeded access to information, knowledge, lifelong learning and culture to the LGBTQ+ community, a group that has been marginalized for years. If they take initiatives to attract people belonging to this community. If they contribute to the socialization, integration and acceptance of people belonging to the LGBTQ+ community by the wider social environment. Finally, if they include material that covers their needs for information, on sensitive issues that concern them, and if they accordingly control their material, so as to avoid the existence of books in their collections with derogatory comments and racist perceptions towards them.
