Most of these books are arranged by subject on the stacks. They can be taken freely from the stacks, but should be left on one of the reshelving tables after use.

ITG staff can borrow books for a maximum period of three weeks, provided these books remain immediately available within the Institute. Students and external parties cannot borrow books.

If this is the case, it is always clearly indicated in the catalogue, at the top of the bibliographic record of the 'missing' book. Other books may have been borrowed temporarily by ITG staff. This can be verified at the counter.

Books not belonging to the ITG library collection can be requested from other libraries [see: interlibrary lending conditions].
