By examining the websites of fourteen public libraries using qualitative content analysis this study aim towards knowledge about how the libraries market that they have implemented a LGBTQ-certification on their library websites. This study is based on the following research questions: How and in which ways has the library which has implemented an LGBTQ-certification market this on its website? How has the library, which has implemented a LGBTQ-certification marketed services and materials aimed at the targetgroup on its website? With the answers to these questions as a basis the study strives to investigate how the libraries marketed and made the certification visible on their websites. The results of the study show that the libraries showed their implemented LGBTQ-certification differently and with varying degrees of visibility and marketing. Some of the libraries in the study do not show anything at the library´s website neither that they have implemented a LGBTQ-certification nor that the library have materials or other services for the targetgroup. Other libraries have a wide scope of marketing and visibility of LGBTQ- materials and services towards the targetgroup.
