Hints for searching

Boolean Operators AND, OR, NOT

When you use the Simple Search, all terms are combined by AND automatically. For a more tightly focused search you may use the Boolean Operators to combine different search terms.

AND: The document has to contain all search terms.

OR: The document has to contain one of the search terms. This function broadens your search and is recommended, when there are different terms for the same meaning.

article OR paper

NOT: This function works excluding and might be useful to reduce a large result list: Documents, which contain the one term, may not contain the other.

article NOT paper

The Boolean Operators work for the Advanced Search as well. You may use them to combine different search terms within one search field. For example, to search for documents of the author "Doe" in the years 2002 or 2003, use the query:

Author: Doe
Year: 2002 OR 2003


In the field 'Search:', you may use the symbols '*' and '?' as wildcards. Use them in place of a character or characters that are unknown or that may differ. You cannot use them in front of a word or search string.

Example 1: chemi* finds chemical but also chemistry or chemist. Example 2: licen?e finds licence and license.

You may use double quotes (") to search for phrases.

Citation of publications from OPUS Geisenheim / URN
Publications in OPUS are in principle equivalent to conventional publications and can therefore be quoted. Electronic publications should be cited according to ISO 690-2. Further information on this topic can be found on the science server of Saarland University Scidok and under project "Digital Dissertations on the Internet".
In accordance with ISO 690-2, electronic publications should be cited as follows, whereby the date is to be understood as the last call to the source by the citing party:
  • Example 1 (dissertations):
  • Sample man, Klaus: Sample man dissertation. - Geisenheim, Univ., Diss., 2014 - [online].
    URN: urn:nbn:de:bvb:20-opus-XXXXX [date]
  • Example 2 (other publications):
  • Mustermann, Klaus: Mustermann text. - Geisenheim : University of Geisenheim, 2014 - [online].
    URN: urn:nbn:de:bvb:20-opus-XXXXX [date]
  • Example 3 (Second publication):
  • Authors: Title. Journal title (year) Volume (issue), pages.
    DOI of the first publication or URN: urn:nbn:de:bvb:20-opus-XXXXX[DateDissertation im Internet”.

URN (Uniform Resource Name)
A URN is assigned for all documents.
The purpose of the URN is to keep your document stable, identifiable and searchable. The URL describes the (physical) storage location of the resource. The URN, on the other hand, does not denote the location where the file is stored, but an entry in the URN resolver of the German National Library, in which the URN and its (current) URL are stored. Advantage: The URN remains valid, even if the physical location of a resource changes (e.g. server change).

Our recommendation: Always quote the URN where you quote your work, not the URL.

Unfortunately, URNs cannot currently be accessed directly using web browsers. Rather, they must first be translated into URLs. This task is performed by the Resolving Service of the German National Library: The URN must be "packaged" as a URL so that the WWW browser can send it to the intermediate resolver. In order to be able to access the document, the name of the resolver must precede the URN. Example:
URN: urn:nbn:de:bvb:739-opus-27610

DOI (Digital Object Identifier)
Similar to the URN, the DOI is a permanent identifier used for citation and linking of electronic objects. The URN is assigned for all publications.
If you would like to have a DOI assigned for your publication in OPUS Geisenheim in addition to the URN, please contact our OPUS Geisenheim contact at the doctoral office: or opus[at]

Contact details of the provider
If you are not the author yourself, please enter your contact details here if you have any queries. This data will only be stored internally.

Metadata can be defined as
- Data that describes one or more resources, or is described as a
- Data that is linked to an object and describes this object.
In principle, metadata therefore represents a description of documents, objects or services and contains information about their content, structure or form.

More abstractly, metadata are descriptions of data or "data about data". Bibliographic records and catalogue entries in libraries can be seen as a form of metadata.
As a basis for the metadata on this document server the Dublin Core Metedata Element Set (short Dublin Core or DC) consisting of 15 basic elements shall serve. Dublin Core is the result of international efforts to find a common consensus on the description of electronic objects (in the broadest sense). The Library of Congress (LoC), the Online Cataloging Library Center (OCLC) and a number of national libraries are engaged in projects with Dublin Core or are about to introduce it.

Publication process
To begin, select the "Publish" menu on the OPUS home page.

Step 1
Then select the document type "Dissertation". You can upload your document(s) directly below. Your publication will be published in the format you selected. The formatting of the documents uploaded to OPUS should correspond to the requirements of scientific work. Additional file formats, e.g. zip, doc(x), xls(x), tex, are accepted for the optional additional submission of the original files of the dissertations.

Afterwards read the guidelines and agree to them by ticking the box. Then please print out the declaration of consent.

Step 2
The upload form follows. Here you will be asked for various data on your publication (so-called metadata), which serve to describe it in catalogues and other bibliographic directories. Describe the document you want to contribute using the predefined categories. Depending on the type of document, some of the fields are mandatory. Otherwise, enter as much information as possible.
For example, the fields are entered:

  • Document type
  • the title of your publication and the language of the title
  • Brief description of the content of your document
  • Standardized and free keywords / keywords
  • the language of the document
  • the license under which you want to publish your document

At the end of data entry, your entries are displayed again and you have the option of correcting, canceling or saving the entries for your document.

Step 3
Finally, send the signed declaration of consent to the OPUS team.
The uploaded PDF file and the accompanying metadata are now in a buffer. The OPUS administration checks the entries and activates the document as soon as the signed declaration of consent has been received. The author is notified by e-mail and receives a confirmation of submission.
All published documents are freely accessible on the Internet.

Requirements for texts and layout / style sheets
Format templates for OPUS publications are not provided. The formatting of the documents submitted to OPUS should correspond to the requirements of scientific work. Please refer to the website for further information.

Technical requirements for the documents / PDF creation
Accepted file formats
Your document must be readable with a standard reader program. The size of the file should be as small as possible. The file name should be as simple as possible without special characters or spaces (e.g. surname_Diss.pdf), since the file name is generally visible after publication. OPUS currently supports several document types including pdf, zip, doc(x), xls(x),tex

If your work contains programs, files, video sequences, sound documents or the like on a CD insert, this should be prepared as a compressed file in ZIP format for publication and should also be uploaded.

No security settings / no DRM measures
Please do not set any security settings in your PDF document. According to a specification of the German National Library, the document must not be copy-protected or otherwise access-protected in order to guarantee long-term archiving of the document.

File size limited when uploading
The system only accepts files up to 250 MB when uploading. If you want to publish larger files, skip the upload of the document during the publishing process and send us the document on CD, DVD, web storage or personally with a USB stick.

Uploading the file(s)
If you have problems uploading your documents, please fill in the form as much as possible and send your file(s) by e-mail to ->

Please submit text documents as PDF/A files if possible = Accessible PDF

Documents in OPUS are usually published in PDF format. In order to ensure long-term archiving, the respective document must be saved in the standardized barrier-free PDF/A format. PDF/A is an international standard that was specially developed for archiving documents. Saving in the PDF/A standard ensures that the file is also readable if it is opened on a computer on which the fonts used are not installed. For this purpose, all fonts and images used in the document are embedded and the metadata is saved in a standardized format.

Create PDF/A documents
You can save documents directly as PDF/A in most word processing programs:
  • Microsoft Word (Version 2007 or later, Service Pack 2): Office → Save to → Publish as XPS or PDF → Options → Check "ISO-19005-1-compatible (PDF/A)".
  • Microsoft Word 2007 without Service Pack 2: Saving as PDF/A works as described above after you install this add-on.
  • Older versions of Word: A direct PDF export is not possible on the part of the program; however, you can use a PDF printing program (see below) or create your PDF file at the workstations in the university library with Adobe Acrobat.
  • File → Export → General → Check "PDF/A-1".
  • LaTeX: With pdfTeX you can also create PDF/A documents.

In Adobe Acrobat (please do not confuse it with Acrobat Reader, where you can only read PDF documents but not edit them), you can create PDF/A documents via File → Save at → Further options → PDF/A. Alternatively, you can download a free conversion program such as PDF Maker (Windows only), which can convert different document types to PDF and PDF/A format.

How to create a PDF/A file (Source: ETH Zurich)
Tips and hints for creating PDF files
  • Please do not provide your PDF with a print or copy barrier. These "security settings" do not protect you against the misuse of your text. In addition, your document will not be included in the full text search of OPUS; your publication is therefore much more difficult to find.
  • All file names should only contain the letters A to Z, the numbers 0 to 9 and the underscore (no umlauts, no accents, no special characters, no spaces). Assign a meaningful, short file name.
  • Make sure that the document properties (file → Properties or file → Document Properties) contain meaningful information about the title and author.
  • Further information on the PDF format and the creation of PDF files can be found, for example, in the online tutorial "Electronic publishing in PDF format" at the Freiburg University of Applied Sciences.
  • The platform provides information on the PDF/A standard (barrier-free PDFs).
  • Please note that it is not possible to integrate audio and video files into barrier-free PDFs. Please contact us if your publication contains such files.

Edit PDF files
Many work steps are only possible with (usually chargeable) PDF generation software such as Adobe Acrobat:
  • Merge multiple PDF files
  • Delete, insert, renumber, or rotate pages in a PDF file
  • Correct minor typos directly in the PDF
  • Preparation of the document for professional printing.

Dissertations / Submission / Confirmation
Dissertations may only be published after they have passed the oral examination and have received printing permission!

If you want to publish a dissertation on OPUS Geisenheim, the doctoral office needs you:
  • the dissertation as a PDF file, preferably in PDF/A format (better suited for long-term archiving and accessibility than simple PDF), see Creating a PDF/A Guide
  • Eight printed and bound copies are requested for the holdings of the library/institute and doctoral office (cf. doctoral regulations):
  • the signed declaration of consent On request, the authors can also upload the file in its original format (e.g. .docx or .tex). This file is not publicly accessible and is for long-term archiving purposes only.

You can register your work via the menu item "Publish" and upload the files. Make sure that the PDF version matches the submitted print copy exactly. For this reason, you should use the PDF file as a print template for the printed copies you require. This guarantees that the formatting of the electronic and printed versions is identical.

Before the final release of your document, it must be confirmed with a declaration of consent (printed and signed),
  • that the Hochschule Geisenheim University is granted the right to store the document, to make it publicly accessible in data networks and, if necessary, to convert it into other data formats,
  • that the publication of this document does not infringe the rights of third parties,
  • that the publication has been approved by the Doctoral Committee and that the electronic version conforms in form and content to the approved original version.

Please hand in the signed declaration of consent together with the printed copies to the doctoral office of the Hochschule Geisenheim University.
It is not absolutely necessary to appear in person in order to hand in the copies;

postal delivery is also possible:

Hochschule GEISENHEIM University
Doctoral Office and Graduate School
Von-Lade-Str. 1, 65366 Geisenheim
Germany (German)

The electronic version and the bibliographical data will be checked and, if necessary, supplemented by the doctoral office of the Hochschule Geisenheim University. Please note: For data protection reasons, the electronic version of the dissertation should not contain the curriculum vitae.
Finally, the dissertation will be published on OPUS Geisenheim and will be accessible free of charge, publicly and without restriction on the Internet.

After publication/activation of the dissertation

The possibly involved examination office of the cooperating partner university will receive a confirmation of submission by post confirming that the publication obligation imposed by the doctoral regulations has been fulfilled.
The author will be informed of the activation by e-mail. At the same time, the electronic publication will be reported to the German National Library in Frankfurt/Main, which registers and archives the publication with the associated metadata.

The dissertation is listed in the catalogue of the library of the Hochschule Geisenheim University.

Second release?

Even if your dissertation has already been published in printed form by a publisher, you can in many cases, after consultation with the publisher, second publish the work on OPUS.
After a first publication in OPUS, you can additionally publish your dissertation in a publishing house. It goes without saying that the publisher must be informed about the already existing publication.

Cumulative Dissertations

Cumulative dissertations can also be published in OPUS.

What is special about cumulative dissertations is that it is often not possible to publish the full text in its entirety because existing publishing contracts prevent this. One makes use of the fact that individual chapters only contain bibliographic references to journal articles that have already been published.
If possible, the articles/essays referred to in the dissertation should be published separately as preprint/postprint versions in OPUS Geisenheim.

Please check whether the preprint/postprint version can be published in OPUS. A list of publishers that allow a second publication in university repositories such as OPUS Geisenheim can be found in the SHERPA/RoMEO list.

If you have any questions about second publications, please contact the doctoral office of Hochschule Geisenheim University -

First and second publication

This category includes essays / articles, preprints, reports, book chapters, books, etc. published in journals or anthologies.

First publication

If you would like to publish an article that has not yet been published, this is usually done as a preprint or working paper.

Secondary publication
You are welcome to publish documents in OPUS that have already been published elsewhere. You will then no longer only publish your research results to the subscribers of the respective journal or buyer of the anthology, but to the public permanently and free of charge (Open Access).

Online publication according to the Open Access principle is recommended by the German Rectors' Conference and the Federal Ministry of Education and Research. The electronic publication is more visible and easier to find.

A study of the British SHERPA project showed that the vast majority of internationally active, renowned publishers such as Blackwell, Elsevier, Kluwer, Springer and Wiley grant their authors the right to parallel publication on their personal website or a university repository such as OPUS Geisenheim.
The conditions for secondary publication on an Institutional Repository vary from case to case. The SHERPA/ROMEO list contains most of the renowned publishers and their basic attitude towards Open Access parallel publications.
Please be sure to observe the legal requirements. This is governed by your contract with the publisher. During contract negotiations, make sure that you as the author do not assign all rights to the publisher, but reserve the right to publish online on a document server. Many publishers only allow secondary publication with restrictions, e.g. after a certain period of time (embargo) or only in the original format. If you are unsure, please contact the staff responsible for OPUS at the doctoral office of the Hochschule Geisenheim University.
Since 1 January 2014 a new secondary publication law applies (§ 38 Abs. 4 UrhG).


The author of a scholarly contribution, which is the result of at least half of a research activity funded by public funds and which is published in a collection which appears periodically at least twice a year, has the right, even if he has granted the publisher or editor an exclusive right of use, to make the contribution publicly accessible in the accepted manuscript version after twelve months from the date of first publication, provided that this does not serve any commercial purpose. The source of the first publication must be stated. Any agreement deviating to the detriment of the author is invalid.
Please refer to this overview of the SUB Göttingen. Here you can see what the new secondary publication law permits.
Publication series
If you would like to publish in an ongoing series, please contact the respective editor.
For the series Geisenheim Berichte contact Gesellschaft zur Förderung der Hochschule Geisenheim, GFHG.

Changing / deleting documents
The possibility of changing or deleting documents is not supported in principle. This guarantees the authenticity of the documents. This makes them comparable to printed publications.
If the author wishes a correction to be made, he must re-introduce the amended document. This corresponds to the process of reprinting printed publications.

The declaration of consent (PDF) regulates the legal relationship between you as author and the Hochschule Geisenheim, acting as publisher.
Your document will only be published (i.e. activated in OPUS) once the signed declaration of consent has been submitted to the doctoral office of the Hochschule Geisenheim University.
Send the declaration of consent by post to:

Hochschule GEISENHEIM University Doctoral Office and Graduate School

Von-Lade-Str. 1, 65366 Geisenheim Germany

Through the consent form and the online publication form, you determine which license applies to your work. Explanations of the licenses can be found here.
The Creative Commons Licensing makes it possible to deviate from certain provisions of copyright law in the sense of Open Access. This is intended to remove barriers to the dissemination of knowledge in the field of research and culture, e.g. in order to make it possible to edit the work in another language.
The rights of use are transferred via individually selectable standard licence models. The author's personal right, i.e. the authorship itself, is not affected by a Creative Commons licence, i.e. the author must be named for each exploitation.

We recommend the Creative Commons CC by 4.0 as the standard license for publications in OPUS Geisenheim. This is the most free CC license, recommended for maximum distribution and use of the licensed material.

  • CC by - Creative Commons License: Attribution 4.0
    This license allows you to reproduce, distribute, and publicly perform the content. Editings may be made and distributed. The content may be used commercially under the following conditions: The name of the author or the holder of the right must be mentioned. The license is based on the international Creative Commons Initiative. The license allows very extensive use and is Open Access compliant.

    Explanations of the Creative Commons licenses can be found on the website:

However, it is also sufficient if you publish only under the conditions stated in the declaration of consent:
  • Standard conditions according to the declaration of consent (without granting further rights of use)
    The author permits the Hochschule Geisenheim to make the electronic version of his or her publication permanently and irrevocably available to the public free of charge on the Internet and on the document server as an Open Access publication.
    You determine which license should apply to your work in the online publication form.

exploitation rights
In the case of an online publication on the document server of the Hochschule Geisenheim, the exploitation rights to the published work for all uses remain with the previous rights holders, i.e. the authors of the work or, in the case of a transfer of rights by the author, with the publishers or exploiters of the work.
The copyright holders merely transfer the simple right of use for online publication and the rights necessary for digital long-term archiving to the Hochschule Geisenheim.
The authors thus retain the right to publish the work elsewhere in print or online.

Rights of use
Documents offered in electronic form via data networks are subject to the provisions of the German Copyright Act (UrhG), unless the author or rights holder has agreed special conditions for certain exploitation rights by granting a Creative Commons License.
According to § 53 of the Copyright Act, the reader is entitled to make personal copies and printouts for his/her own scientific or non-commercial use. In addition, the copyright law (§§ 44a - 63a UrhG) applies.
Any further use requires the express, prior and written permission of the author or the holder of the right. The user is responsible for compliance with legal regulations. He/she may be held liable for misuse.

Long-term availability and safety
The publication is stored and archived in OPUS Geisenheim as a PDF file. This file is protected against manipulation. For long-term, globally unambiguous and location-independent referencing, i.e. for permanent searchability and citation, each document is assigned a "Persistent Identifier" (Uniform Resource Name) according to the urn:nbn scheme of the German National Library in addition to the URL.
In principle, the permanent and free availability of the documents is aimed at; however, they are guaranteed to be available for at least 5 years. The archiving beyond that depends on the availability of the format, the viewing software as well as the conversion possibilities. The finally published documents can no longer be changed or deleted.

International standards such as the guidelines of the Open Archives Initiative (OAI) are used and further developed for the indexing, storage and archiving of electronic documents. Statistics evaluate the number of accesses to each document per month, the use of the publication server per day and the indexing by search engine robots per month.
In order to achieve an effective content search on a national and international level, each publication is indexed by bibliographic and technical metadata according to the Dublin Core format as well as by at least one abstract, a classification and keywords. These data are to be provided by the author. In order to ensure a uniform quality standard, the metadata may be processed by the OPUS team of the Hochschule Geisenheim University in the form of additions and corrections. The documents are accessible and searchable via different sources, currently they belong to it:
- OAIster - search in over 1,100 freely accessible document servers worldwide
- BASE - Bielefeld University's multidisciplinary search engine for scientific Internet sources
- Catalogue of the German National Library (with the exception of dependent works, e.g. essays)
- Catalogue of the Geisenheim Library (with the exception of dependent works, e.g. essays)
- Search engines such as Google and Google Scholar
