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.

How do I publish my work here?
Please click on the publication link on the start page.
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.

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.

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.
Authors can choose which terms of use must be regarded for their publication. These terms are defined in a license. This repository supports different licenses, from which you can choose one (i.e. Creative Commons Licenses/).

1. Aims and criteria pertaining to the Publication Server at the Goethe University Frankfurt am Main
  1. The Document Server serves all members of the Goethe University Frankfurt am Main with the organizational and technical back-up for immediate electronic publication and long-term storage of academic research which is highly relevant for research and teaching. It supports fast communication in the science community world-wide and promotes barrier free access to subject specific information in the sense of Open Access.
  2. In addition, the publication system serves as a document server for publications derived from the special collection areas, which the University Library Frankfurt am Main is responsible for: Africa südlich der Sahara, Ozeanien, Allgemeine und Vergleichende Sprachwissenschaft, Allgemeine Linguistik, Allgemeine und Vergleichende Literaturwissenschaft, Germanistik, Deutsche Sprache und Literatur, Israel, Judentum, Theater und Filmkunst, Biologie.
  3. The service is maintained solely by the Electronic Services Department at the Frankfurt University Library.
  4. The electronic documents comprise quotable Persistent Identifiers in the form of URN addresses which are supported by the German National Library’s Resolving mechanism and enable permanent admission to resources. Access is via the national and international library catalogues, search engines, OAI service providers and other reference tools. Long-time storage of theses, diploma and master dissertations as well as their original documents are thus provided.
  5. Operation and development of the document server are closely linked with national and international initiatives and projects such as the Open Archives Initiative, Dublin Core Metadata Initiative or the German Initiative for Network Information (DINI).
2. Legal Framework
  1. The author grants the operator of the document server
    • the right to store electronically, especially in databases,
    • to convert for long-term storage or visualization with respect to maintaining content ( the original archiving remains intact)
    • and in the case of publication to apply simple rights of use for public access to international data networks according to § 19 c UrH Gesetz.
    • the right to register and transfer the document to a long-term archive for storage
    • the right to enable metadata, especially abstract and index of content, to be accessible by every one to use.
  2. The operator is obliged to support the author with their publications, to archive the documents and to maintain permanent access bearing a justifiable amount of effort in mind. The contents of the documents are exclusively the responsibility of the author or the agent.
  3. Authors or publishers are obliged if possible to clarify any potential copyright or exploitation of rights of a third party or to procure their agreement. If the author has knowledge of the existence or the development of legal obstacles he is obliged to inform the University Library without any hesitation. The University Library is not liable for damage which results from the violation of copyright or the exploitation of rights as far as there is no known deliberate gross negligence.
  4. The author’s copyright is maintained. Publication on the University Library’s document server does not preclude publishing the documents in journals or monographs or on other servers. According to the recommendations of the Wissenschaftsrat on digital information supply via universities all scientists at the University of Frankfurt are requested to behold the right to self-archiving in the Institutional Repository as well when signing contracts. More information as pdf document at, page 26 Greifswald 13, July 2001).
  5. The metadata of those documents published on the document server can be accessed by everyone via OAI, stored and if necessary expanded or in selection made available to a third party.
  6. Documents already published will not be deleted from the server.
3. The electronic document
  1. The term “electronic document” is understood in the sense of these guidelines as a document which is based on text and graphics, is stored in digital form on a data carrier and is disseminated via computer networks. The publication of multimedial documents, which comprise audio and video sequences, is also possible.
  2. An electronic document which is published on the document server has to fulfill the following conditions:
    • It is intended to be disseminated publicly.
    • It is not a dynamic document. If changes need to be made then the changed electronic document will be stored as a new document.
4. Rules for archiving electronic documents
  1. Academics, scientists, students and other people who are connected with the University can publish their current publication in a given data format in the archive. Any change to the content of document made thereafter is out of the question.
  2. The following categories of electronic documents can be stored:
    • Publications by members of the GU which have scientific content as in articles (pre- and post-prints) monographs, parts of monographs, public lectures, science reports, studies, serials
    • Publications by members of the GU such as collections, electronic journals (ejournals ) and conference papers
    • Publications and series of affliated organisations and people associated with the Goethe University
    • Significant speeches and lectures pertaining to the history of the GU as in the rector’s address or an inaugural lecture
    • Documents which have to be published according to the examination specifications (dissertations and habilitations)
    • Final examinations of students at the Goethe University (i.e. diploma, bachelors, masters, and state examination)
  3. For the formal cataloging and subject specific cataloging of the electronic document national and international defined standards and interfaces like Dublin Core Metadata Standard, the guide lines of the Open Archives Initiatives OAI or the norms of METADISS of the German National Library implemented. The metadata are those as given by the person, who wants to archive the document, in the online form and are checked by the library, corrected and, if necessary, adjusted by the library. Norm data are taken from the anchored online key word norm database of the German National Library. (SWD) and can be supplemented with additional key words in German and English. The author of a dissertation or thesis is obliged to give an abstract in at least one foreign language. The documents are designated a subject group classification as per the Dewey Decimal System (DDC).
  4. Archived documents will be made accessible in the internet proved that there are no legal barriers.
5. Technical aspects of the document server
  1. The documents will be given permanent and individual Persistent Identifiers in the form of URN addresses which enable immediate access to the document.
  2. The preferred presentation format is currently PDF (ideally PDF/A).
  3. The electronic documents are retrievable in local, regional and national library catalogues via search engines and with OAI service providers ( e.g. OAIsterOAIster). On the part of the document server bibliographic metadata and full text are already retrievable.
  4. Der Dokumentenserver erfüllt als eingetragener OAI-Dataprovider die Anforderungen des OAI-PMH in der Version 2.0.
6. Organisatorische Regelungen
  1. The content and technical aspects of the document server at the Goethe University Frankfurt am Main is operated by the University Library Johann Christian Senckenberg Frankfurt am Main.
  2. Electronic publication is free of charge.
  3. The document to be disseminated electronically can usually be sent by using an uploaded form on the document server.
  4. Additional work necessary to prepare the document ready for inclusion on the server or conversion into another format will be carried out by staff at the University Library in Frankfurt am Main.
  5. Contact for all enquiries concerning the document server is the IT department at the University Library in Frankfurt am Main.

7 facts which you ought to know about Open Access

  1. All subject relevant open access journals are listed in the DOAJ –directory of Open Access Journals.
  2. Not only can you publish in Open Access Journals but also in Open Access Archives and Repositories as well. These archives, including the Frankfurt am Main document server, are listed in ROAR–Registry of Open Access Repositories and in DOAR – Directory of Open Access Repositories.
  3. Placing an article on the document server only takes a few minutes. Test this yourself.
  4. Most publishers permit their authors to place their documents on the Universitys’ open access publishing platforms. Check with your publishing company whether this type of self archiving is permissible. More information about publishers and their reaction to a parallel online production are in this Sherpa-Romeo list under:
  5. Fewer and fewer publishers reject to publish an article ('Ingelfinger Rule') if it has already been published on a University’s server.
  6. Open Access published articles reach a greater audience than those articles published in expensive journals and increase the desirable Impact Factor of your academic scientific work.
  7. Open Access protects copyright because he who publishes his work early on in open access documents rather quickly his intellectual copyright as opposed to hitherto forms of publishing processes which often takes months, if not years.
Put into practice the principles of Open Access and publish (parallel) on the Document Server of your University.
