While holding the left mouse button and dragging the cursor left or right, you can have a panorama view.

In the open stacks, the books are lined up in chronological and numerical order, by year of purchase. Signatures consist of a number e.g. 2020 (for the year of purchase), a letter A or B (depending on size and / or format of the book) and a consecutive number.
Please follow the labels and signs for orientation.
