Our Wikimedian-in-residence, Mr. Šarevski, is already a volunteer MANU Library, and is constantly using materials for editing articles on Wikipedia, increasing the volume and pace. The library's fund includes more than 160.000 units of which 56.310 books and 110.000 volumes of journals from different fields of sciences and arts. Having this in mind, the work of Wikimedian-at-residence is of great importance for making valuable contributions to Wikipedia with accurate, reliable and scientifically sound referenced information and data on various topics. Moreover, our Wikimedian-at-residence has provided a few hard copies of the book Atomic Physics published by MANU for the needs and work of the project Educational programme 15/16 and Shared Knowledge. He has also signed an agreement that the MANU Library in the future, will also provide its publications for permanent possession for the needs of the projects of Shared Knowledege and Wikipedia. Beside the constant help from Library employees that provide the books, documents, photos and materials, our Wikimedian-at-residence has direct contact with the academicians, scholars and scientists at the institution. In the three resident weeks so far, Wikipedia has at least a dozen new or improved articles with files uploaded on different themes such as geography, physics, archaeology, ethnology, history etc.
