This paper is intended to compare information retrieval (IR) educational goals in different academic and professional areas such as Library and Information Science (LIS) and Health Sciences (HS), analysing and identifying a shift on user seeking goals in the digital era and, eventually, on educational goals as well. It starts with a section on information literacy where several aspects are specified, such as user goals, IR systems, IR skills, information seeking strategies (queries) and user perception of search success. Another section focuses on teaching IR aspects, like IR educational goals, assessment and feedback, and e-resources in LIS and in HS. Teaching in an academic environment for academic audiences is somehow different from teaching for professional audiences even though these are located in an academic environment as well. Those are the issues and particularities that throughout the analysis of information literacy and teaching IR aspects will be explained along the full paper.
