IJBF Online

Here you will find instructions for searching the IJBF Online and explanations of the individual search functions.

Search

You have the following options for searching.

Search form

The search form allows you to search using various search criteria. To do so, select the appropriate criterion in the search field and enter your search term(s) in the search field. The following search criteria are available:

1. Full Text: Searches in all entries for the entered terms. Finds all entries that contain all searched terms and therefore returns the most results. For a more specific search, the other search criteria are more suitable.
   
   The following operators can be used in the search field:
• *: Added to a string. Searches for entries including all terms that match the searched string with any addition.
• AND: Searches for entries including all the terms connected by this operator (default search function).
• OR: Searches for entries including at least one of the terms connected by this operator.
• NOT: Searches for entries including the first, but not the second of the terms connected by this operator.

These operators can be combined with each other.

2. Title: Finds all entries whose titles contain all searched terms. This search criterion can be used to search specifically for entries for particular terms. Search with truncation does not work at the moment.
3. Author: Finds all entries with authors of the searched name. Suggests up to 15 matching author names in alphabetical order as you type. This search criterion can be used to search for entries by specific authors.
4. Keyword: Finds all entries to which the searched keyword is assigned. Suggests up to 15 matching keywords in alphabetical order as you type. This search criterion can be used to search for entries that deal with a specific topic.
5. Subject: Finds all entries that are assigned to the searched subject area. Suggests up to 15 matching subject areas in alphabetical order as you type. This search criterion can be used to search for entries that belong to a specific subject area.
6. Publication Year: Select Exact to search for a single year, or Range to search for a range of years. Finds all entries that have been published electronically in this year or range of years.
7. Periodical/Series: Finds all entries that are assigned to the searched periodicals/series. This search criterion can be used to search for entries that have been published in specific periodicals/series.
8. Publisher: Finds all entries that are assigned to the searched publisher. Suggests up to 15 matching publishers in alphabetical order as you type. This search criterion can be used to search for entries published by specific publishers.
9. Place: Finds all entries which contain the searched place. Suggests up to 15 matching places in alphabetical order as you type. This search criterion can be used to search for entries in which specific locations are mentioned.
10. ISBN/ISSN: Finds all entries that belong to the searched ISBN or ISSN. This search criterion can be used to search specifically for the bibliographic data of entries that originate from a particular publication.
11. Volume: Finds all entries that were published in a volume with the searched number. This search criterion, in combination with the search criterion “Periodicals/Series”, can be used to search specifically for the entries of individual volumes of certain periodicals/series.
12. Abstract: Searches within the abstracts. Finds all entries whose abstracts contain the searched terms. This search criterion can be used to find the bibliographic information of entries with specific content focus.
13. Entry Language: Select a language from the drop-down menu. Finds all entries which are written in this language.

Please note: The search is not case sensitive. Truncation does not work currently in title search.

You have the option to apply several search criteria at the same time. To do this, click on "Add row" in the search form. This creates a second search field in which you can set another search criterion (or else the same one). You can create as many additional search fields as you like.
If you use more than one search field, the search will find all entries that match all search criteria (“Search for all of these terms”) (AND). Instead, you can also select “Search for any of these terms” (OR) above the search fields, which will cause the search to find all entries that match at least one of the searched criteria.
By clicking on "Add NOT" you create a search field to which you can assign a search criterion. Terms entered in this search field will be excluded from the search. You can add this search field as often as you like.
By combining the above functions, you are able to perform very specific searches.

Example

You want to search the IJBF Online for all entries that mention the word "Artefakt" and that match the subject “Archäologie”. However, you want to exclude the publication place “Rahden” from the search. For this you use the search form as follows:

1. Create a second search field via "Add row".
2. Select the search for "all of these terms" (default option).
3. In the first search field, select the search criterion Full Text and enter the search term "Artefakt".
4. In the second search field, select the search criterion Subject and enter “Archäologie”.
5. Create a third search field via "Add NOT". This is marked with a "NOT".
6. Select the search criterion Place in this search field and enter “Rahden”.
7. After clicking on "Search" you will see 10 out of 36 hits in the results list.

Results list

The results that match your search are listed on one or more pages. The number of search results as well as the search criteria can be found above the results list.

Each search result consists of the title of the entry, author(s) if existent, access information, entry type, online publication date (print publication date in brackets, if applicable), the cover of the database as well as a button to download the PDF ("Download PDF"), if available, and a text preview showing relevant text passages and highlighting the searched term in yellow (only for Full Text search criterion).

You can access a search result by clicking on the title or cover of the database. If you do not have access to the database, please log in first.

The search results are sorted by relevancy (frequency and weighting of the searched terms). You can also sort by date ("New to old" or "Old to new") or by title ("A to Z" or "Z to A").
Furthermore, instead of the default 10 results per page, you can also display 20, 50 or 100 results per page.

The search results can be further restricted under "Filter Results". Various filter options are available for this:

1. Access: This option filters the search results according to who can access them. By default, "All content" is found. It is possible to filter by "Licensed content", "Open Access", "Publicly available" as well as "All available content".
2. Subject
3. Publication year
4. Place

All filters can be combined with each other. Filtering by certain filter options excludes further certain filter options if there are no entries which match both options.
