What is ePublications?

ePublications is the publication server of TH Köln and can be used by all members of the university to publish their scientific documents. Students can publish their final theses, if applicable also student research projects or project work, online via ePublications. Students need the consent of their reviewer. The reviewer confirms the quality by signing the publication contract.

What does Open Access mean?

Open Access means publishing scientific literature and other materials electronically and making them freely accessible via the internet. Further information on Open Access can be found here: Open Access an der TH Köln und unter open-access.network.

The TH Köln supports the principles of Open Access and underlines this by adopting its own Open Access Declaration. The university is thus following the recommendations of many science and research funding organisations.

Documentation and technical support
This document server is based on the repository software OPUS 4. OPUS is documented here: https://https://www.opus-repository.org.
Hints for searching

For most queries in Cologne Open Science, the simple or advanced search by title or author is sufficient. You can narrow down your search further in the advanced search or in the hit list by using filters, e.g. by document type. You can also display the search results in different ways (e.g. in ascending order by year of publication).

It is also advisable to search via the Browsing function. You can select a specific filter and continue searching only the relevant documents.

With the simple search, several search terms are automatically linked with "and". For a more specific search, it is advisable to link several search terms with the help of the Boolean operators (AND, OR, NOT).

AND: All search terms entered must occur in the document (e.g. sight AND view).

OR: Only one of the entered search terms must occur in the document. This function extends the search range and is useful if different terms exist for a topic (e.g. sieht OR view).

NOT: This function has an exclusionary effect and can be used to limit the number of hits: In documents in which one search term occurs, the other must not occur (e.g. sight NOT view).

Wildcards: If you are not sure how to spell a search term, for example a name, or if you want to extend your search, you can use * and ? as wildcards. It is not possible to use them at the beginning of a search term.

Phrase search: You can use double inverted commas (") with expressions to search for a fixed phrase (e.g. "Japanese cherry blossom").

Reading/Printing documents

To be able to read or print the documents, the free software Acrobat Reader is required.

How to cite?

To permanently address the publication, please cite the DOI (Digital Object Identifier) or the URN (Uniform Resource Name). These can be found in the Frontdoor of a publication in the metadata of the lower section.
The date to be entered is the last time the source was called up by the citing person.

Unfortunately, URNs currently can´t be called up directly with web browsers. To translate them into URLs, the Resolving Service of the German National Library is required. Therefore, prefix the actual URN with the abbreviation https:/nbn-resolving.org/ to access the document.
The same applies to calling up a DOI. Here, the abbreviation https://doi.org/ precedes the actual DOI.

Electronic publications can be cited as follows:

Advantages of an Open Access publication via ePublications

Publications can be found easily and quickly on the internet. In addition, all documents are referenced in the catalogues of the university library, the union catalogue of North Rhine-Westphalian libraries, the German National Library as well as in academic search engines such as BASE and databases.

Open Access publications are easier to find and are therefore not infrequently cited more frequently than publications published in print. All electronic publications on ePublications receive a Uniform Resource Name (URN) at the German National Library. Under this address, every publication is permanently retrievable and thus also citable. The University Library of the TH Köln ensures long-term archiving of the documents as PDF files at the German National Library. Currently, a period of at least five years is guaranteed.

A publication via ePublications is free of charge. After the formal criteria have been checked by the university library and the publication contract has been submitted, the document is published online within a short period of time and can therefore be cited immediately. Unlike with commercial publishers, with ePublications authors retain their second publication right. They merely transfer the simple right of use to the university library for one-time publication via ePublications.

How do I publish my work here?

First fill out the publication contract and send it printed with your original signature to the publication service of the university library.

Students please send the original signed publication contract by mail to their supervisor with the request to forward it to us by internal mail.

Then click on "Submit" button. This will take you to the So gelangen Sie zum Publication form.

First you are requested to choose a document type. Right beneath that you can upload your document files. Having done so you may click on "send". What follows now is the actual form. You have to fill in data about your publication here (so called metadata), which is used to describe your work in catalouges and other bibliographic directories. Describe the document you want to upload using the categories and fields on the publication form. Depending on the document type, some of these fields are mandatory and therefore have to be filled in. Please describe your document as clear as possible. Mandatory fields are for example:

  • the document type (must be choosen from a list)
  • the title of your publication and the language of the title
  • the abstract of the document
  • the publication date of your document (normally the day you publish it online)
  • the language of the document (must be choosen from a list)
  • the licence, under which you want to publish your document (must be choosen from a list)

If you are unsure what to fill in certain form fields, you can point the cursor on a field and an explaining help text will be shown.
After you have finished the form, all data will be displayed once again for a check-up and you then have three possibilities: you can correct them if necessary, add your document to a collection or simply safe it directly.
The data will then be checked by the staff at the university library. We will contact you if we have any queries. If all the information is complete, the document is finally released by us on the document server and is thus published.

In oder to publish your work cookies have to be enabled in your web browser.

What's metadata?

Metadata can be defined as

  • data describing one or more ressources
  • or as
  • data associated with an object and describing it

Basically metadata is describing documents, objects or services and contains information about their content, structure or form. More abstractly metadata is a description of data or "data about data". Bibliographic data sets and catalog entries in library catalogs can be seen as a kind of metadata.

This repository is using metadata in the Dublin Core Metedata Element Set (short Dublin Core (DC)) which has fifteen basic elements. Dublin Core is the result of international efforts to reach a collective consensus in describing electronic objects (in the broadest sense). The Library of Congress (LoC), the Online Cataloging Library Center (OCLC) and several national libraries are dealing with Dublin Core in many projects and are close to introduce the system respectively.

How I create a titlepage? What about my personal details?

On the title page or in the title line, the title of the publication, the author and the year of publication should be mentioned. When publishing theses or dissertations, please also remember to remove any personal information on the title page, such as matriculation number or contact information, from the pdf before uploading. An uploaded pdf cannot be changed afterwards. Can a publication be deleted or changed?

In which format are the documents published?

Text documents are published in PDF format. Please use the following syntax for the file name if possible: Surname_Title.pdf (Ex: Mueller_Großbauprojekte_verstehen.pdf).

PDF/A was developed as an international standard especially for archiving documents. This ensures that the file can also be read on computers where the fonts used are not installed.

Conversion into a PDF/A document is now possible directly from many text editing programmes.

To enable long-term archiving, it´s not allowed to upload files any password and/or copy protection.

There is no size limit for uploadable files. If your publication exceptionally requires a high resolution or if contractual requirements of a publisher require copy protection, please contact us in advance: Publication Service.

Edit/Deleting documents

Documents published via ePublications cannot be subsequently edited or deleted. This guarantees the authenticity of the documents, which are comparable to printed publications. If a correction is necessary or desired, the changed document must be completely re-submitted. This corresponds to a new version or an edited version in the case of printed publications.

As an author, you can generally choose whether you want to publish your documents via ePublications as a first publication (so-called "golden path") or as a second publication (so-called "green path") in the Open Access procedure. Further information on the publication paths can be found here.

By publishing via ePublications, the university library is only granted the simple right of use for publication on the Internet. On the part of the university library, this means that further publication with publishers, journals and other servers is possible.

In the case of a first publication via a publisher, it should be checked which rights of use and exploitation or blocking periods have been contractually agreed with the publisher. SHERPA/ROMEO provides an overview of publishers with information on the respective transfer of rights.

This does not necessarily conflict with publication on our document server. The library explicitly points out that the observance of copyright is an obligation of the authors.

In any case, please check whether your contract permits publication on our document server! You can do this, for example, with the help of SHERPA/ROMEO.

With the first publication via ePublications, the author only transfers to the university library the simple right to publish on the internet, so that a second publication via a publisher is therefore possible at any time.

The copyrights of a publication always remain with the authors. They only transfer to the university library the simple right of use for one-time publication via ePublications and thus retain their right for second publication. In return, you grant the university library the right to store the documents, to make them publicly accessible electronically worldwide and, if necessary, to convert them into other data formats or to make copies. You can also additionally transfer this right to others, i.e. they also publish your work elsewhere.

The library explicitly points out that compliance with copyright and usage rights is the responsibility of the authors. The authors assure the university library in the publication contract that they have observed the copyright and do not violate the rights of third parties (e.g. when using illustrations).

All documents published on ePublications are open access documents and are licensed with CC licences. As an author, you can use Creative Commons licences to define the rights of use of your publication for the public. For more information on Creative Commons licences, click here.
