The aim of the project “Poland for Researchers” (hereinafter the Project) is to create a potential-based digital e-service Polona for Researchers (hereinafter the PDN service) with a high level of maturity, which will significantly improve the work of scientists, especially work with source materials and significantly improve access to the results of scientific works. The Project will provide a modern and universal platform for communication between participants of research projects, which use digitised objects in their research. Solutions will be introduced to identify individual research projects and to interact with them. E- PDN will provide new features based on services and resources of over 3 million publications currently provided by Digital Repository BN (RCBN). Essential functions: 1) creation of scientific texts in the built-in editor 2) ergonomic work using a virtual, personalised work desk allowing to organise work with multiple sources at the same time 3) the use of specialised tools (e.g. manipulation of image parameters, synchronisation of displays) 4) embedding new research tools created in BN in cooperation with other entities 5) use of external services supporting research work 6) management of the research team with consideration of project scheduling 7) Introduction of scientific texts and publications of scientific texts in cooperation with other entities 5) use of external services supporting research work 6) management of research team with consideration of project scheduling 7) Introduction of scientific texts and publications of scientific texts in cooperation with other entities 5) use of external services supporting research work 6) management of the research team including project scheduling 7) Introduction of scientific texts and publications of scientific texts in cooperation with other entities 5) use of external services supporting research work 6) management of the research team including project scheduling 7) Introducing new research tools created in BN in cooperation with other entities 5) use of external services supporting research work 6) management of research team including project scheduading 7) Introduction of new research tools created in the BN in cooperation with other entities 5) use of external services supporting research work 6) management of the research team including project scheduling 7) Introduction of scientific texts into the development of Scientific Texts in cooperation with other entities 5) the use of external services supporting research work 6) management of the research team including project schedues 7) Introduction of new research tools created in the BN in cooperation with other entities 5) the use of external services supporting research work 6) management of the research team with consideration of project scheduling 7) Introducing new research tools created in BN in cooperation with other entities 5) the use of external services supporting research work 6) management of the research team with consideration of project scheduing 7) in the implementation of scientific texts and projects created in B in cooperation with other entities 5) use of external services supporting research work 6) management of research team including project scheduing 7) Introduction of new research tools created in the BN in cooperation with other entities 5) the use of external services supporting research work 6) management of the research team with considerations of project planning 7) Introduction of new research tools created in BN in cooperation with other entities 5) use of external services supporting research work 6) management of the research team including project schedule 7) Introduction of The project will also make necessary modifications of existing systems for the functioning of the created PDN e-service.
