        Why Open Access?

        In the context of the Internet, Open Access is the principle that the results of scholarly research should be made generally available online without cost or restrictions.

        Every user is supposed to have at least read-only access to the published content.

        In the wake of the 2003 Berlin Declaration on Open Access to Knowledge in the Sciences and Humanities [Link: http://openaccess.mpg.de/Berlin-Declaration], a growing number of political and scholarly institutions have been encouraging and supporting the application of this principle.

        Opus Koblenz-Landau is committed to the policy of “free open access”. This means that the contents can be read by anyone at no charge, but beyond that, the author’s copyright is not impaired or restricted in any way.

        In most cases, authors will even be free to re-publish Opus documents with a commercial publisher.

        For more information on OA see e.g. the Open Access Dictionary or the Open Access platform

        What are the advantages of publishing via OPUS Koblenz-Landau?


        Publications will be accessible worldwide any time and free of charge.


        Publications are searchable both by metadata and full text. They will be listed in our library OPAC and meta-catalogues such as KVK. Full text can be retrieved on our OPUS server and via national or international search engines.

        Long-term preservation

        Protected against manipulation, OPUS documents will be stored for an indefinite period of time. This qualifies them as being reliable sources of citation. A Uniform Resource Name (URN) will ensure safe and permanent identification of each document. In addition, all OPUS documents will be preserved in the digital archives of the National Library (available in German only).


        Publication is free of charge. It will save you both the expense and the time you would have to invest into publishing in print.


        Recent analyses suggest that OA publications are likely to win higher citation rates than publications that are available in print only. So it is reasonable to expect that your work may be appreciated more widely if published via OPUS. On the pages of  the Open Citation Project, you will find the subject of impact analysis covered in great detail.

        Who is entitled to publish documents via OPUS Koblenz-Landau?

        Generally speaking, all students and members of staff or faculty may submit their work free of charge. For student work, e.g. (non-doctoral) theses, authorization by the Betreuer (faculty referee or supervisor) is required.

        Search Tips

        Boolean operators AND, OR, NOT

        In the Simple Search, AND combines individual search terms by default. Use one of the other operators for a more specific query. Operators must be entered in capitals.

        AND (or space) will retrieve only those documents that contain all search terms combined in this way. In other words, adding search terms will reduce the number of hits.

        OR will return all documents that contain at least one of the search terms entered. This means that additional search terms will enlarge the number of potential hits. The operator enables you to include synonyms or related terms:

        sofa OR couch

        NOT will omit all documents that contain the search term immediately following it. Using this operator allows you to exclude specific terms:

        sofa NOT couch

        Boolean operators can also be entered in the categories of the Advanced Search. You can use them to combine search terms within a particular field. Supposing you want to find documents written by Mr or Mrs Smith and published in 2002 or 2003, your query would be

        Author: smith

        Year: 2002 OR 2003


        Use wildcards * and ? if you wish to include alternative or related spelling. * may stand for any number of omitted characters, including zero, whereas ? requires exactly one character to replace it. Wildcards cannot be applied in the initial position of a search term.

        libra* will get you to Libra, library, librarian, and librarianship

        organi?e will return organise and organize

        Search by a particular phrase by putting it into quotation marks:

        „John Smith“ will retrieve all documents containing the name in this word order.

        What are the requirements for a publication via OPUS Koblenz-Landau?

        Authors are required to supply

        For further requirements concerning doctoral and postdoctoral theses, see Special regulations for dissertations.

        Your PDF document

        Please submit your document containing all illustrations, charts, tables, etc. in PDF format if possible. For correct indexing and display, UTF-8 encoding is recommended.

        File size

        For technical reasons, the size of an individual file is limited to 100 MB. If your document happens to exceed this limit, we request you to submit it divided up into a number of smaller files. Copyright regulations prevent the Library from manipulating your work in this way. The maximum size per document is 200 MB. Documents having an overall size larger than 200 MB may be submitted on CD or DVD. In this case, please complete the regular submission form (as described following the question How do I register and submit my document? ) but omitting the actual uploading procedure.

        No DRM protection tolerated

        We cannot accept documents protected in any way against copying or other forms of access. Long-term archiving is only possible if the files are ready to be transferred to other data carriers any time.

        File names

        Please try to find a concise name for your files, e.g. Diss.pdf., avoiding spaces or special characters. The names of published files will be visible to the general public.

        Submission statement

        The library needs written authorization for publishing your document. Therefore, authors are asked to confirm that they agree to the terms of use and copyright policies of OPUS Koblenz-Landau. Please fill in the submission statement form print it out, and sign it. You may send it to the OPUS librarian responsible for your campus, or simply hand it in at the library information desk.

        Special regulations for dissertations

        For the submission of doctoral and postdoctoral theses, a number of printed copies are required in addition to the online document. The number of deposit copies, their layout and other specifications are defined in the examination regulations of each faculty (Fachbereich).

        Please note that the contents of the PDF version must be strictly identical with the printed original, as signed and approved by the examination committee. The easiest way to achieve this is to use the PDF file as the master for your printed copies. In this way, you can be sure that wording and format of both versions are the same.

        Doctoral candidates may hand in the deposit copies at the information desk, together with the signed submission statement.

        Do not submit a dissertation before it has been defended successfully in the oral part of the examination.

        How do I upload files using an off-campus computer?

        For reasons of security, uploading electronic documents is only authorized from within the University LANs. External computers, such as the PC at your home, need to be logged on to the University network via VPN first. For details, see the instructions provided by our computer centres:

        Koblenz: https://www.uni-koblenz-landau.de/de/koblenz/GHRKO/netzwerk/vpn

        Landau: http://www.uni-koblenz-landau.de/de/landau/rz-landau/stud-info/vpn

        If you are not sure about the IP address of the device you are using you can check it here: http://www.wieistmeineip.de Upload is expected to be possible from current IP addresses beginning with 141.26 or 139.14, respectively.

        I have just submitted my thesis. What happens next?

        The descriptive data of newly submitted files will be checked by library staff and corrected or completed if necessary. None of these data will be accessible to users at this stage: actual publication is suspended until the signed print-out of the submission statement has reached the library. But when it has, we try to publish the files without delay.

        Following publication on the OPUS server, the National Library will receive deposit copies of all published files and metadata for additional long-term storage and retrieval.

        back to top



        How long will I have to wait for my submission to get published?

        We do our best to process your document at short notice. But do not forget that we can only proceed on the basis of your submission statement. When we have received that, you can expect publication to be imminent.

        back to top



        I need a written confirmation that my thesis has been submitted successfully. How do I get it?

        We can acknowledge the receipt of your submission as soon as we have both the document itself and your submission statement. Requests for confirmation may be adressed to the OPUS librarian in charge. In Koblenz, you may also ask our staff at the information desk for a receipt when you are handing in the submission statement in person.

        Can I add corrections to an OPUS publication or withdraw it altogether?

        The value of repositories like OPUS Koblenz-Landau consists, for a great part, in data integrity and reliable citation. For this reason, documents are expected to remain as they were at the date of publication, and may not be corrected or withdrawn afterwards. In case of errors so grave as to make corrections inevitable, a separate and corrected version may be submitted. As a result, both versions will be available simultaneously. The procedure is analogous to publishing a corrected edition of printed work: anyone holding a copy of the imperfect original can continue to cite it, alongside with any other editions that happen to be in circulation.

        back to top



        Can I enclose attachments in formats other than PDF?

        As a rule, only PDF files are accepted for publication. Please contact us if you wish to include supplementary materials in a format other than PDF, e.g. .doc(x), .xls(x), .rtf, or .zip. We will check if upload is possible in such a case.

        back to top



        Can I impose access restrictions on my OPUS publication?

        Restricting access to a limited group of users, e.g. campus-only or other selected IP ranges, is incompatible with the principles of Open Access. In the case of dissertations, an additional reason for not accepting restrictions is that publication is obligatory. Limited access would violate this obligation.

        back to top



        Does my thesis have to include a curriculum vitae?

        Whether or not your thesis needs to contain your curriculum vitae, depends on the regulations of your faculty (Fachbereich). A CV can be presumed to be optional unless explicitly required there.

        Please bear in mind that the online version of your thesis must correspond to the exam copy in every detail of its contents. Hence a CV contained in the printed copy is expected to appear in the OPUS document as well. We strongly advise you not to omit anything without permission. Instead, refer to your examiners to see if there is a legal way of leaving anything out. For instance, you may be allowed to drop the CV in both published versions of your thesis.

        Generally speaking, a curriculum vitae is supposed to outline your academic career and general experience rather than your private life. Try to avoid including data you would regret to see circulating in the Internet and indexed by search engines, e.g., your date of birth, your address, your telephone number, etc.

        back to top



        Is it safe to quote from an OPUS document?

        OPUS documents are equivalent to conventional publications in many respects, including citation.

        There are various citation systems. Style guides generally advise authors to adopt one particular citation style and to use it consistently throughout an individual work.

        back to top



        Why is a URN attributed to each OPUS document?


        Documents published via OPUS Koblenz-Landau carry both a ‘web adress’ URL and a Uniform Resource Name URN. The URL locates the actual site of an individual source, which may change, whereas the URN identifies the resource persistently and is not going to change even if the resource has been transferred elsewhere, for instance, to a new server.

        Web browsers cannot access resources directly by URN but require an ‘interpreter‘ that can match the URN of a resource with the URL of the site where it is currently stored. In the case of OPUS, this service is provided by the National Library’s URN resolver.

        Can I publish a preprint or postprint?

        ´In most cases, it is legal and even desirable to publish pre- or postprints of journal articles. Many publishers will not object to an open-access publication after a certain waiting period has expired. The policy followed by your publisher in this respect is defined in the publication contract between you and your publisher. It can also be found in the SHERPA/RoMEO List.

        back to top



        Can I publish a compilation thesis?

        Yes, you may submit an article thesis or ‘thesis by publication.’ But make sure early on that you hold the copyright to each part of the dissertation. Negotiating an individual article with your publisher, you should insist on retaining the right to re-publish it. Otherwise you must ask your publisher for a licence to include that article in your thesis.

        back to top



        How do I register and submit my document?

        Make sure your browser accepts “cookies”.

        Then select „Publish“ from the frontpage menu. Submission is in three steps.

        First, you will be asked to select the type of your document and to upload files.

        Having acknowledged the terms of use and copyright policies, you can register your document by completing a number of metadata fields. Categories marked with an asterisk (*) are obligatory. Please try to describe your document in detail. There is a special field for questions or comments in case you are not sure if your entries have been adequate. Cut and paste these special characters if they are not on your keyboard:

        ä ö ü ß Ä Ö Ü

        Finally, all your entries will be listed for a last revision. Please check them carefully before completing your submission.

        Can I export metadata from OPUS Koblenz-Landau?

        Metadata may be exported to reference management programmes such as Citavi or EndNote in formats RIS or BibTeX.

        On the frontpage of each document, you will find both a RIS and a BibTeX button. If your target is Citavi, click on ‘Open with’ and select Citavi in the pop-up window. State or confirm the character encoding of the source, which is usually UTF-8. In the Citavi import window, which now opens, select the title and click ‘Add to project.’ It will now be on the list shown on the left side of the Citavi interface.

        For further information on exporting bibliographical data with Citavi or EndNote, see e.g. the tutorial compiled by Technische Universität München, TUM.

        Can my work be published both via OPUS Koblenz-Landau and by a commercial publisher?

        If you plan to send your work to a commercial publisher first, you must make sure that your contract will allow you to provide open access to the content on repositories such as OPUS Koblenz-Landau. In many cases, this is possible after a certain waiting-period has expired. The SHERPA/RoMEO list will tell you what policy your publisher has adopted in respect of self-archiving.

        Conversely, publishing your work via OPUS Koblenz-Landau will not restrict your property rights in any way. You are free to re-publish your work elsewhere, e.g. as a book, as a journal article, or on other servers.
