Check the index lists to ascertain whether the database contains a certain search term, or how a search term is written. Index lists are available for the following search fields in the Advanced Search:

-          Persons / Names

-          Institutions / Organisations

-          Geographical index

-          Subjects

-          Occupations / Fields of activity


You can browse the index lists, search for entries and go straight to the entries. The index terms can be transferred to the search form very simply.


Calling Up Index Lists

To the right of each input field equipped with an index list, you will find a link designated Index. Clicking this link opens the index list belonging to this particular search category.


Browsing Through Index Lists

The index entries are numbered consecutively. A navigation bar directly above the index entries indicates which index entry you have opened. Using the arrows pointing to the left and to the right, you can browse through the list. With the Go function you can go directly to an index entry. Enter the number of the required index entry in the navigation bar’s input field and click the button Go.


Searching Index Lists

Enter a search term in the input field above the navigation bar and click Search. All index entries containing the search term will be listed.


Please Note:The index entries contain no accents, umlauts or other special characters. Instead of ä, ö, ü enter the alternative forms ae, oe, ue, and use ss instead of ß. When searching the index, do not use any hyphens or apostrophes, which occasionally occur in the index. Using punctuation marks will not yield any results.


If you wish to combine several search terms, the operators AND, OR and NOT can be used for searches in the index lists. When no Boolean operators are entered, all search terms are automatically combined with AND. The wildcard characters, question mark and asterisk, can also be used when searching indexes.


Go To specific Index Entries

With the Go To function, you can go directly to specific points in the index.

Enter the first word or first letter, or number of the desired index term. Click the button Go To The index page beginning with the character(s) entered – according to the alphabetical or numerical sorting – upon which the entry is found (or, if none was found, upon which it would have been found) will be displayed.


Selection and Transfer of Index Entries

Index terms are selected by clicking the box to the left of the term. The search term will be transferred to the list Selected Entries to the right of the index list.


When the selection of search terms in the index is complete, transfer the selected term(s) to the search form by clicking Submit selections. To combine more than one selected term in the search form the operator OR is used.


Individual entries can be deleted from the list of selected entries by clicking the red cross beside the entry. If several terms have been selected, all the selected terms can be deleted by clicking Clear selections.
