Sign language starts out as a mother tongue for a community of people, the deaf. It develops like the rest of the languages, presenting variants and concepts defined by Linguistics (science that studies language) as well as characteristics conferred by the history of the deaf and their geography (nationality), making it as rich and valuable as any other. The Portuguese Sign Language collection brings together scientific content from areas such as language sciences, neurosciences and educational sciences, adapted and translated into Portuguese Sign Language. There are 24 book + DVD manuals initially created to transmit the curricula taught in the Portuguese Sign Language Degree at the Universidade Católica Portuguesa, always combining the Portuguese version and the respective adaptation in Portuguese Sign Language. The Portuguese Sign Language Degree was entirely adapted for profound deaf people who, through blearning methods, obtained competences and higher academic training which resulted in a highly differentiating factor in their insertion in the labor market. The degree gave rise to a master's degree highly specialized offered by the Institute of Health Sciences of the Universidade Católica Portuguesa and all the work carried out between 2008 and 2012 to materialize the Portuguese Sign Language collection created deep roots in the research carried out by deaf academics and aimed at the deaf community.
