Discovery - Search Tips

Discovery is the University of Erfurt's search portal for comprehensive literature research.

Discovery systems are modern search engines in libraries. Under one search interface a library’s stock of literature and other media, articles and full texts from licensed databases and journal portals as well as free electronic texts can be found.

A discovery system is as easy and intuitive to use as Google and literally promotes one thing above all else: the discovery of knowledge and information.

"Discovery" is:

  • easy access to printed and electronic resources
  • through responsive web design ideal for mobile devices such as tablets and smartphones
  • with integrated user account management

The basic database for the Discovery system is the K10plus Central. This index contains our holdings as well as those of 400 other libraries of the Common Library Network (GBV). In addition, it currently contains more than 57 million articles and more than 34 million electronic resources.

We look forward to your feedback! Write an e-mail or use our online form.


Search terms Enter one or more terms in the search slot. The "Autocomplete" function supports you in selecting the search terms.

Narrowing down the search result Period, type, format By means of a slider or by manually entering the desired years, the result can be narrowed down to a selected period. By activating the desired checkboxes, the search result can be narrowed down to a specific publication type (e.g. electronic) and to selected media formats (e.g. book).

Search queries and search result Confirm search queries by clicking the search button. The entered terms are searched simultaneously in all fields of the title description (person, title keyword, keyword etc.). By default, the search result is sorted by relevance ranking, the highest possible match of the search query with the available data. It is possible to change the sorting by year of publication.

Access to Licensed Electronic Resources For a variety of electronic resources, the library offers access to the electronic full text. Follow the links provided. Access to licensed electronic resources (e-books, e-journals, e-articles) from outside is possiblefor members of the University of Erfurt, especially for students and employees via Shibboleth or VPN.

Placeholder ? The character ? can be placed anywhere in the search term or at the end of the search term. It replaces exactly one character. Example: - Publi?ation finds publication and publication - W??mar finds Weimar, Wismar etc.

Person search Preferably, when searching for a specific person, enter the name in quotation marks. Example: "Gerd Röpke".

Original written search If titles are available in original written form, then you can search for them in this way. Example: История текста и биография А. П. Платонова

Phonetic search Phonetic search can also be used to find similar terms. This is helpful when the correct spelling of a name or term is unknown. Example: Tollsdeu finds Tolstoy, Tolstoj, Tolstoy etc.

Known problems

The Discovery search portal is continuously improved, existing problems are fixed and functionalities are optimized. We are aware of some problems whose solution has not yet been realized. For example, the individual volumes of a journal are not displayed completely and are not sorted chronologically. Availability of individual volumes, e.g. whether a book is currently at the bookbinder or missing, is not displayed. If you have any questions, please do not hesitate to contact us at the information desks. For the functionalities that are not yet or not reliably offered in Discovery, please use the library's online catalog .
