The task of the modern school is to prepare students for a world that is dynamic and full of different information from different sources. In this forest of information, it is necessary to find exactly the relevant one, and the one that best meets the requirement. Research learning is extremely important in the education of a future successful person. Exploratory learning enables the student to cope independently with the new challenges that await him at every step. It is necessary to valorize the relevant information well and determine exactly the one that gives the best answer to the set task. In the implementation of research learning is extremely important the so-called third space. That third space for learning in school is the school library. Today, a modern school library should be able to respond to all the requirements of modern education, including the requirements of research learning, and it thus becomes a center of information in every school. This paper presents successful projects created by conducting research learning in collaboration with primary school teachers and school librarians. These projects are related to reading, searching for information from various sources and creative response to the demands created by research learning. It is extremely important for successful research learning that the school librarian has a good collaboration with the teachers and the principal in school.
