The Library will be closed between the 23rd of December 2024 and the 1st of January 2025. Our library's services will be available from the 2nd of January 2025.

Due to the relocation of our external warehouse the books and doctoral dissertations stored there, as well as the entire stock of the library's periodicals, will be unavailable until the beginning of January 2025. Many of our books are still available for loan and current literature can be found on the open shelves.

Hirsch-index The h-index was invented in August 2005 by Jorge E. Hirsch, a physicist at the University of California (San Diego) and it is a simple measure of citation.  A researcher’s Hirsch-index is h, if there are h articles that have at least h references to each. Therefore, if a researcher’s h-(Hirsch-) index is 21, then he/she has 21 publications to which at least 21 citations have been made separately.
