Each year several executive committees award the annual Brill, Elsevier, Van de Sande and Juynboll fellowships. The fellowships allow scholars from home and abroad to conduct research in the Special Collections of Leiden University Libraries under the aegis of the Scaliger Institute.
The Juynboll Foundation and the Scaliger Institute of Leiden University Libraries have founded a collaborative fellowship program to enable one or two scholars to study the Arabic and Islam special collections of Leiden University Libraries.
The Van de Sande fellowship focuses on the study of the history of pharmacy, botany and medicine. Proposals for the fellowship are welcomed by the board.
