Until further notice, the Circulation Desk at the TIB Technology/Natural Sciences site is only open from Monday to Friday from 13:00 to 15:00. At the TIB Sozialwissenschaften (Social Sciences) and TIB Conti-Campus sites, lending and returning items is possible Monday to Friday from 09:00 to 15:00 and registration from 10:00 to 12:00. The reading rooms at the TIB Conti-Campus site are open to a limited number of people Monday to Friday from 9:00 to 15:00; all other TIB sites and reading rooms remain closed.
In its Patents and Standards Reading Room, TIB has large collections of standards issued by German (e.g. AD, BAZ, DVGW, FGSV, VDE, ZVDH), international (ISO, ITU) and foreign (ASTM, JIS, SIA) institutions.
Members of Leibniz Universität Hannover may use the Perinorm Online database featuring full-text access to VDI guidelines and DIN standards (exception: standards labelled VDE).
Non-members of Leibniz Universität Hannover can make or order copies of VDI guidelines on special VDI photocopy paper. An extra fee of € 0.65 per page is charged for this service.
DIN standards can be viewed on site. However, copies may not be made.
As a rule, individual standards are not listed in the TIB portal. For this reason, when ordering standards, please select the option "Order without search" and enter all available details in the order form.
