Why publish in HFTor?

As the university's own repository, HFTor offers the possibility of publishing one's own scientific work free of charge with permanent proof and findability, especially as open access, in the most common search services. Works published in HFTor are visible nationally and internationally via the following services:

  • BASE
  • COAR
  • Google
  • Google-Scholar
  • OpenAIRE
  • DataCite
  • DNB-Katalog

In HFTor, URN (Uniform Resource Name and is used for the unique and permanent addressing of documents on the Internet) is assigned automatically. Open-Access marking: In accordance with DINI requirements, open access documents are specially marked in the search display. The prerequisite for this is that the document be assigned to the "open access" collection.

Can you publish in HFTor only as open access?
If an open access publication is not desired or possible by copyright, the work/document can be entered in HFTor with an access restriction. A bibliographic record is (possible) without full text access. If you as an author wish to have restricted access, please select "No" in the entry form under Open Access and let us know (link to contacts) the type of access restriction you wish to have.
Who can publish?
In HFTor, HFT researchers, professors, students and other employees can publish their scientific works.
What can be published?
The following document types can be published in HFTor: Scientific article, thesis (bachelor and master), book, part of a book, conference publication, contribution to a periodical (newspaper, journal, proceedings), teaching material, diploma thesis, dissertation or habilitation, exam paper, image, lecture, master's thesis, moving images, patent, periodical, issue (Ausgabe) of a journal, preprint, report, review, audio, student research project, working paper, miscellaneous (miscellaneous resources, non-text marked).
How long do the publications remain available online in HFTor?
In HFTor, there is no time limit on availability. Electronically published dissertations are forwarded to the archive server of the German National Library and archived there for the long term. The German National Library collects online dissertations and postdoctoral theses. The DNB guarantees long-term preservation and permanent access by, among other things, assigning the URN.
Search tips

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.

How does publishing in HFTor exactly work?

Basically, there are the following steps of publication:

  • Selection of the document type and (optionally) loading of the file(s).
  • Enter the metadata based on the selected document type.
  • Check inputs and confirm - or back to change inputs.
  • Review and approval by the repository operator.
  • In these instructions(link to the file) for recording scientific publications in HFTor (among others for the annual research report) you will find detailed descriptions of the publication process.

DOI allocation
HFTor offers the possibility to automatically generate and register Digital Object Identifiers (DOI - a unique and persistent identifier for any object, e.g. a publication or a research dataset). The hfTOR associates DOIs at the document level and not with (individual) files.
What file formats can be uploaded?
The following file formats are supported in HFTor: PDF, txt, HTML, HTM, JPEG, Doc, Docx
What must be considered when publishing theses?
Students have a possibility to deposit their theses as a digital copy on the institutional repository - HFTor. Important: The thesis must meet the prescribed quality criteria or receive the recommendation for publication from the supervisor.
What is metadata and why is it important?

Metadata are data that contain information about other data or data that are associated with the object (scientific work) and describe this object (e.g. form, content, persons, page number, etc.).

In somewhat more abstract terms, metadata are descriptions of data or "data about data." Bibliographic records and catalog entries in libraries can be seen as a form of metadata. The more precisely the metadata is recorded, the easier it is to find the work/document.

When publishing in HFTor, metadata are the components of the bibliographic description of the documents. The basis for the metadata is the international Dublin Core Metedata Element Set (Dublin Core or DC for short).

Can the documents in HFTor be deleted or modified?
Works/documents already published in HFTor cannot be modified or deleted. If you wish to make a correction, you must publish the modified work/document as a new edition.

The transfer of the rights of use is necessary for a lawful publication in HFTor.

The HFT Library cannot provide legal advice.

Check if embargo deadlines of the first publication are met.
In most cases this is no problem. Please ensure in any case, if your publisher allows a parallel publication! To do that you can use the SHERPA/ROMEO list.

You decide which terms of use should apply to your work/document.

One of the most effective tools for licensing are so called Creative Commons and these licenses are offered by HFTor.
