What are the differences between the different account types?

Although reference lists can be used with a standard account, licensed content such as electronic full texts and factiva cannot be accessed. This kind of access requires an account for political scientists. Search functionality is available without registering an account.

Who can register for an account for political scientists?

In order to be able to use licensed content via Pollux, a researcher in political science must be employed at a university or non-commercial research institution in Germany or be a member of a German political science association. The FID Political Science office will check whether the account is authorised to use licensed content after registration.

When can an account be used after registration?

After successful confirmation of the email address, you can immediately log in with your Pollux account to use the reference lists. The activation for the use of the licensed contents takes place promptly after the authorisation has been checked.


Can a standard account be converted into an account for political scientists?

The type of account can be changed. When changing from a standard account to an account for political scientists, however, the access authorisation must first be checked by the FID Political Science office. For the conversion of an account, please contact

Can I change the password of an account?

The password can be changed in the user settings under "Account" after the old password has been entered. Additionally a password can be changed using the "Forgot password?" function when logging in.

Technical requirements

What are the technical requirements for using Pollux?

Only a web browser is required to use Pollux. We support all recent browsers, e.g. Mozilla Firefox, Google Chrome, Microsoft Edge, Apple Safari. Internet Explorer is outdated and therefore no longer supported.


What are alerts?

Alerts draw attention to literature and datasets that have been newly integrated into the Pollux search space. Only entries that correspond to the individually defined search criteria are displayed. For example, it is possible to be informed only about new books on the subject of "Middle East conflict". In the search definition, it is possible to set filters that can, for example, limit the media type.

How often are alerts updated?

An alert is updated if new entries have been integrated into Pollux that correspond to the defined search criteria of the alert. Pollux constantly updates the search space with new entries.

How do I know if there are new entries for my alert?

If new entries for alerts have been found, a notification appears for registered users next to the menu item Alerts in the navigation bar.

Example: 34

What can I do if an alert returns too many or too few results?

The result set of an alert depends on how generally the search query is defined. The preview provides an overview of the potential result set. Using the preview, it is possible to adjust the search query according to requirements.

Can alert entries be exported?

The alert entries can be exported by selecting "Export all entries" when the alert is open. This option is only displayed if entries exist. You can also export displayed results directly using the Export button.

How many alerts can be created?

There is no limit to the number of alerts.

Reference Lists

What are reference lists?

Reference lists can be used to permanently save and manage hits from search queries or alerts. For your convenience, an initial reference list is automatically created and available from the moment the account is set up, while further lists can be created as required. Saved titles can be moved between lists.

Can reference lists be exported?

Reference lists can be exported to files using the .ris data format via the option under the menu item "Actions".

How many reference lists can be created?

There are no limits to the number of reference lists that can be created.


Who can use Factiva?

Every user with an account for political scientists can access the Factiva database via Pollux. An exception are political scientists, who already have access to the database via the following institutions:

Researchers who can gain access through these institutions will be redirected to the respective registration page of their institution for Factiva.

How is Factiva used?

As an introduction to the use of Factiva, the following video tutorials are available:


Who can use Polit-X?

All users with an account for political scientists (PLUS account) can access the Polit-X database free of charge via Pollux.

What is Polit-X?

Polit-X is a data-driven political monitoring and analysis tool that provides you with an extensive database of political documents and other entries at federal, state and European level. By means of an alert function, a daily updated and automated monitoring via e-mail is also possible for your search terms.

What options do I have for using Polit-X?

There are two ways to use Polit-X via Pollux.

You can directly access the Polit-X database and use the following functions there in particular:

If you want to use the other functions of Polit-X, you can create a personal account. This includes the following functions in particular:

Which contents can be found in Pollux?

Pollux contains political science publications such as monographs, articles from journals and collective works as well as Open Access data from the BASE database and the Social Science Research Network (SSRN). So far, the licensed monographs include titles from Cambridge University Press, Oxford University Press and Berghahn Books.

How can the full texts of search results be accessed?

The level of access for a particular record is indicated both on the overview page of the search results and on the full display of the record. If a licensed full text is made available to political scientists, a link "Full text via Pollux" is displayed. Further access options are "Full text" and "Subito", where access via Pollux is not possible. In the case of "full text", the user's local library could offer this full text if necessary, while "Subito" can be used to deliver documents for a fee.

How can I download ebooks provided on the EBook Central platform?

The EBook Central (EBC) platform provides the titles of the publishers Berghahn Books, Pluto Books, Verso Books and Zed Books. Every logged-in and and verified user with an account for political scientists can read online via the platform. However, an EBC account is required to download chapters and full texts in PDF format. The account must first be activated by the Pollux office, but can then be used immediately when further EBC titles are called up. Accounts created by other institutions for the use of EBC cannot be used to access EBC ebooks via Pollux.

Who can I contact if I have further questions?

If you have any questions about Pollux and its functions, please contact

What search options are available in Pollux?

In Pollux, Boolean operators, placeholders and phrase search can be used for the search. For the Boolean operators 'AND' or '+', 'OR' as well as 'NOT' or '-' can be used. Without inserting Boolean operators, all words of up to three search words are linked with 'AND' by default. With more than three search words, half of the search words must be contained in each case, so that these are displayed in the results. Placeholders are '?' for one character and '*' for several characters. These can be used at the end and also within a word, but not at the beginning of a word. A search for a specific phrase is possible using double quotation marks ("...") to specify the complete phrase text.

Advanced search allows searching in specific fields using boolean operators in an easy way. All searches are phrase searches and the extended search syntax cannot be used.

What is extended search syntax?

In Pollux you can now design your search very precisely. Thanks to the extended search syntax, all field codes (document properties) available in Pollux can be specifically selected in the search field. The alerts can thus also be defined very precisely.

Which search fields are available in Pollux?

Following fields can be used for search:

authorAuthorauthor:"Cheng, Christine"
title:"multilateral governance"
year:[2000 TO *]
year:[* TO 2000]
year:[2000 TO 2007]
languageLanguage (ISO 639-2)language:ger
doiDOI (Digital Object Identifier)doi:10.1142/9789814366984_0009
keywordKeywordkeyword:"Political indicators"
typePublication type (article, book, book_chapter, journal, newspaper, oa, dataset, blog, blog_entry)type:book
publisherPublisherpublisher:"Oxford University Press"

All fields can be combined using Boolean operators (AND, OR, NOT).

How do the placeholders (truncation) work?

With * you can define several characters as wildcard, with ? you can define single characters as wildcard.


Following search examples demonstrate how to use extended search. It is important that there are no spaces between the field identifier and the query term:
