The holdings of the Duisburg-Essen University Library are distributed among six branch libraries according to subject content and are freely accessible there.
The system of classification is an enumerative system. The notation frame ranges from AAA to ZZZ (three-letter code), plus a fourth letter for further subject specification if necessary.
You can search for specific topics and media via our Primo catalogue.
Printed journals can be found in all subject libraries, arranged in subject groups. With a few exceptions, journals cannot be borrowed.
In addition, there is access to approx. 40.000 electronically licensed and approx. 66.000 electronically freely available journals.
Group study rooms and zones can also be found in all branch libraries. The rooms vary in size and are suitable for small group work.
Numerous PC workstations are available in all branch libraries.
You can use the PC workstations to access the electronic services licensed by the library.
Authentication is required to access external, non-library sources. Please authenticate yourself by entering your university ID (= Unikennung) or your user number and the respective password.
Large areas on both campuses are equipped with a wireless network (WLAN). This means that you can access the internet in all branch libraries with your own laptop via a wireless connection.
If you have problems with the WLAN, you can contact the e-Points in the Humanities and Social Sciences Library and the LK Library.
Where do I find more computer rooms at the UDE?

In the other subject libraries, please go to the lending desks.
How long is the loan period? How do I find out when the loan period ends?
The loan period is initially 28 days. You can borrow the media for up to one year in total, but you must regularly extend the loan period.
You can find out about borrowed titles and loan period dates at any time via your library account.
If you have provided an email address, we will remind you by email 10 days before the loan period expires of the return date and the timely renewal. Once a month, you will receive a complete account overview by email.
The pre-reminders and the account overview are free additional services and do not release you from the obligation to check the loan periods of the borrowed books in order to avoid exceeding the loan period.

How come sometimes I can't reserve media?
You can only reserve copies that have actually been borrowed. Therefore, first check whether there are other copies that are not borrowed.
Some holdings, such as reference holdings, cannot be reserved.
How do I get a book or journal from the stockroom?
Dissertations, over-formats, rarely used books or journals worthy of protection are in the closed stacks and are not directly accessible.
Books on loan and reference copies can be ordered via the Primo catalogue.
Periodical volumes and special volumes, so-called periodical piece titles, can be ordered directly if required:
How can I cancel a reservation or a stockroom order?
You can delete reservations via your library account in Primo:
- Call up Primo and log into your library account.
- In the section "Orders + Reservations" you will find a list of your orders.
- Select the link "CANCEL" next to the respective title.
You cannot cancel orders from the stockrooms and from the other campus via the campus delivery service (CaLD) on your own.
To do so, please contact the lending desks or send an email to:
What if a book is not on the shelf?
Books that are not in their place on the shelf may, for example, be in use at one of the study places, in the reading area, at the photocopiers, etc., as they can be taken from the shelf by anyone interested.
If a copy cannot be found after repeated searches, you can report it missing at the information desk or the circulation desk of the subject library concerned. As soon as the title is marked as "missing" in the catalogue, you can order it from another library via interlibrary loan.
Semester collections are set up at the request of UDE lecturers to support courses and contain books from our holdings from both campuses. They exist for at least one semester and are set up as reference stock in the respective branch library.
You can see whether a book is in a semester collection in the Primo catalogue in the location display. In the column "Status" you will find the entry "Semesterapparat" and below it the number of the relevant apparatus.
Copies and scans can be made on site, but lending is not possible.
As an alternative or supplement to the conventional semester collection, UDE lecturers have the option of setting up an electronic semester collection. Here, for example, digitised journal articles or book excerpts can be made available to the participants of the course. Usually, there is also a list of recommended literature, relevant links to the topic and materials from the seminar.
Where do I find semester collections?
Semester collections are placed in the LK Library near the information desk on the 1st floor and in the BA and MC Libraries near the lending desks.
You will find the semester collections on the first floor (room A) of the Humanities and Social Sciences Library and in the MNT and Medical Libraries near the lending desks.
What are service reference collections?
For the special needs of research and teaching and the official requirements, UDE lecturers are offered this special borrowing option.
Media can be loaned to UDE lecturers indefinitely for the duration of the employment contract and are not available to users. Media borrowed for reference are marked accordingly in the Primo catalogue and given a fictitious deadline date (30/12/99).
Primo can be used for literature research free of charge and without personal registration.
Login is required to view your library account, renewals, reservations, etc.
Students and UDE staff members whose university ID is already linked to the library account log in via Shibboleth with their university ID and the corresponding password.
Other library users and UDE staff members whose university ID is not yet linked to the library account log in with their user number and password.
How do I know on which campus the media is available?
The location of the book or journal is preceded by a "D" for a branch library at the Duisburg campus and an "E" for a branch library at the Essen campus.
The holdings of the UL are arranged in the branch libraries according to a system of arrangement based on content and subject-related aspects and are freely accessible there.
In the Primo catalogue, you will find a link to the classification system in the upper navigation. Select the desired subject area there (e.g. psychology) and via the main groups of the subject (e.g. social psychology) you will get to the individual system point (e.g. HUP, role behaviour). Selecting the notation (system point) "HUP" leads directly to a hit list in the catalogue.
Alternatively, you can also search for any keyword in Primo and note the system location in the case of matching hits (in the above example, HUP). If you now select the search field "Notation" from the pull-down menu in the advanced search and search for the system location HUP, you will also receive a complete overview of the titles available there.
The thematic search via Primo or the classification system has the advantage over browsing the shelves that you will find all the titles for a system location, i.e. also the titles that are currently on loan and that you can reserve.
Why can't I find a shelfmark for some titles?
For some publications, the shelfmark is not always displayed in the usual place in the location information.
For multi-volume works, please switch to the full display first (by clicking on the title). Click on the link "Show related volumes", which is located at the bottom under the heading "Links".
In case of journals, you can find the shelfmark in the full display in the "Holdings" line. Alternatively, you can select the coloured symbols below the title to get an overview of the printed or electronic availability.
Newly ordered titles are also displayed in the catalogue without shelfmarks. You may receive further information, e.g. ordered, cancelled, out of stock or similar.
What does the status reveal about the media?
In the stock display, you will find the columns Status, Borrowed until and On shelf to the right of the shelfmark.
Borrowable media are marked as loan stock. In this way you can recognise special features, e.g. reference stock, missing, stockroom loan, permanent loan, media centre, reference library etc.
If the title is currently on loan, you will see the end date of the loan period here.
If the item is not on loan, you can open the shelf finder by clicking on the arrow. It shows you exactly on which floor and on which shelf you can find the item.
Can I order media for collection at the other campus?
Can I return borrowed media at the other campus?
Media can be returned to all branch libraries, regardless of whether they were ordered via the campus delivery service or borrowed by hand.
Items can also be returned to the other campus during service hours (only in the Humanities and Social Sciences Library and in the LK Library!).
Media from the Humanities and Social Sciences Library can also be borrowed again from the subject library Medicine.
How does the internal article delivery service work?
UDE students and staff members can order articles from journal volumes that are only available at the other campus or are in the closed stockrooms via the internal article delivery service. External users are excluded from this delivery service.
Articles from journals marked with an order reference in the Primo catalogue can be ordered.
For the purpose of research and teaching, education, further education and professional work, you have the possibility to order books and articles from books and journals that are not in the holdings of the UL via interlibrary loan.
We will notify you via email as soon as the ordered item arrives.
The loan period is determined by the supplying library, is usually 28 days and begins on the first day of provision.
What does interlibrary loan cost? How do I pay?
For each book or article order, a flat-rate charge of 1.50 € is levied (exceptions).
The flat-rate charge for ordering a book, a book article or periodical article are debited to your user account automatically.
In addition, there may be extra charges if an article of more than 20 pages is delivered from a library outside NRW. The default setting adds up to 8.00 €. You can decline completely or choose a higher limitation.
The information about extra charges can be found on page one or two of your order. If the charged amount is within your chosen setting, the additional charges will be added to your user account.
How do I order media via interlibrary loan?
Please also note our information:
Can I cancel orders?
You cannot cancel orders that have already been placed.
If you have accidentally placed an order via interlibrary loan twice or no longer need the title, please contact the information desk by email (firstname.lastname@example.org).
The flat rate for expenses incurred must also be paid in the event of cancellation.
Licensed services and products (databases, electronic journals, e-books) can be used by university members without any restriction and independently of the provider from outside the campuses.
Why can't I use e-resources?
Please note that a large number of databases, journals and e-books are only available to UDE members for licensing reasons.
In our listings, offers requiring a licence are marked with a yellow dot. Freely available journals and databases can be recognised by a green dot.
