At the IMS there is a library specialising in two main fields. One concerns the creation of a library devoted to the work of El Greco, Italian (mainly Venetian and Roman) painting of the 16th C and Spanish painting of the 16th-20th C. The library has already been expanded with journals, unique in Greece, which were purchased with funds donated by the Anastasios G.Leventis Foundation, 3E Company and donations from the Spanish Ministry of Culture, as well as the Zentralinstitut of Munich.
Furthermore, important monographs on El Greco have been donated to or purchased by the library, and there are catalogues of major exhibitions which have been organised in Greece and abroad.
