Anonymous Data Collection

You can visit the webpages of the ZBW without telling us who you are. We only get to know the name of your internet service provider, the website from which you came to our website and which of our webpages you visit. This information will be used for statistical purposes. You as an individual customer remain anonymous.

Collection and Processing of Personal Data

If you call up pages and files on this website and are requested to input data about yourself, we will advert you that the transmission of these data over the internet is unsecured and can therefore be noticed or even falsified by unauthorised persons.

Utilisation and Circulation of Personal Data

The personal data collected on the webpages of the ZBW will only be used without your consent for the execution of contracts and in order to process your enquiries. Beyond this, your data will only be used with your prior consent for advertising and market research and the tailoring of electronic ZBW services to customer requirements. Equally, your data will only be used for tailoring individualised advertising if you have granted your consent. Your data will not be circulated to third parties. You can revoke your consent at any time, effective from the time of revocation.

Individual advice

The ZBW offers an individual chat and e-mail reference service on literature and data search, library use and other library services. For the chat, you can enter a name or an anonymous alias (optional). For e-mail communication, an e-mail address is required. In addition, your IP address is recorded for protection against misuse of the service. This information is stored for 3 months, for the further processing of your request and for the security of the systems, and then automatically deleted. Your e-mail questions and chat dialogues are anonymised manually after 3 months. The anonymised data is stored permanently to improve our service and for research purposes.

For this service the ZBW uses LibAnswers from SpringShare LLC. A data processing agreement with the provider has been entered into. The data is processed on servers in Ireland and stored there in encrypted form. Please also note the provider's privacy policy..

The General Data Protection Regulation (GDPR) prescribes legal standards in particular for the usage of service providers not based in the EU. In these cases, your personal data will possibly be transferred to the USA and processed there. American companies have engaged to comply with EU data protection standards by means of the EU-US Privacy Shield. You can find more information about this at

It will not be used for other purposes or transmitted to third parties. We also advise you that unauthorised access and falsification are possible if e-mails are transmitted without encryption.

Video conferences

The ZBW uses video conference services in order to conduct meetings, events, online seminars or telephone conferences, during which personal data will be processed. The type of personal data depends on which data you enter on the relevant provider’s platform prior to or during the conference. For example, the following data may be processed:

Personal details: first name, last name, e-mail address, password, telephone number, profile photo
Meeting data: designation and description of the conference, IP addresses, device information
When joining by telephone: telephone numbers, connection details

When using the chat function, the text you enter will be processed and may be stored until you delete it manually. When using the audio and video function, the images recorded by your video camera and your audio data will be passed through the provider’s servers and will be processed for conducting the conference. You may disable your camera and microphone during a conference at any time using the settings of your computer. The video conference services enable the recording of conferences. In principle, the ZBW will not record any conferences. If the ZBW should deviate from this in individual cases, you will be informed of this comprehensively prior to the recording and, if required, we will request your consent.

The legal basis for the processing of the personal data in the scope of video conferences shall be Article 6 (1) (e) of the GDPR in conjunction with Section 2 of the Foundation Formation Statute of the ZBW. The ZBW will process personal data of employees in accordance with Section 15, subsection 1 of the data protection law of the German federal state of Schleswig-Holstein. If events are held on the basis of a contract, Article 6 (1) (b) of the GDPR shall form the legal basis.

The ZBW will not pass on your personal data on to third parties unless expressly communicated in advance. During the conferences, your personal data (such as first name, last name, video and audio data) may be – at least partially – inspected by the participant.

Please contact the provider directly in order to obtain information from them or to exercise your rights in relation to them. The data protection information and contact details of the providers are set out below:
