  3. General information on data processing
    1. Scope of the processing of personal data

      We only process personal data of our users if this is necessary to provide a functional website as well as for our contents and services. The processing of personal data of our users takes place regularly only after consent of the user. An exception applies in those cases where prior consent cannot be obtained for real reasons and the processing of the data is permitted by law.

    2. Legal basis for the processing of personal data

      Insofar as we obtain the consent of the data subject for the processing of personal data, Art. 6 para. 1 lit. a EU General Data Protection Regulation (GDPR) serves as the legal basis.
      In the processing of personal data required for the performance of a contract to which the data subject is a party, Art. 6 para. 1 lit. b GDPR serves as the legal basis. This also applies to processing operations that are necessary to carry out pre-contractual measures.
      Insofar as the processing of personal data is required to fulfil a legal obligation to which our company is subject, Art. 6 para. 1 lit. c GDPR serves as the legal basis.
      In the event that the vital interests of the data subject or another natural person require the processing of personal data, Article 6(1)(d) GDPR serves as the legal basis.
      If processing is necessary to safeguard a legitimate interest of our company or a third party and if the interests, fundamental rights and freedoms of the data subject do not outweigh the first-mentioned interest, Art. 6 para. 1 lit. f GDPR serves as the legal basis for processing.

    3. Deletion of data and storage time

      The personal data of the person concerned will be deleted or blocked as soon as the purpose of storage ceases to apply. Furthermore, data may be stored if this has been provided for by the European or national legislator in EU regulations, laws or other provisions to which the person responsible is subject. The data will also be blocked or deleted if a storage period prescribed by the aforementioned standards expires, unless there is a need for further storage of the data for the conclusion or fulfilment of a contract.

  4. Provision of the website and creation of log files
    1. Description and scope of data processing

      When using the adlr.link website, an encrypted browser connection is established to ensure secure data transmission.
      In principle, you can visit the adlr.link website without telling us who you are. However, every time you visit our website, your browser automatically transmits data and information from your computer system to us.
      The following data is collected:

      1. Information about the browser type, language and version used
      2. The user's operating system
      3. The IP address of the user
      4. Date and time of access
      5. Contents of the request
      6. Access status code
      7. Websites from which the user's system reaches our website
      8. Websites accessed by the user's system via our website
      9. Amount of data transmitted


      The data is stored in the log files of our system. This data is not stored together with other personal data of the user.

    2. Legal basis for data processing

      The legal basis for the temporary storage of data and log files is Art. 6 para. 1 lit. f GDPR.

    3. Purpose of data processing

      The temporary storage of the IP address by the system is necessary to enable the website to be delivered to the user's computer. For this the IP address of the user must remain stored for the duration of the session.
      The data is stored in log files to ensure the functionality of the website. In addition, the data serves us to optimize the website and to ensure the security of our information technology systems. An evaluation of the data for marketing purposes does not take place in this context.
      Our legitimate interest in data processing pursuant to Art. 6 para. 1 lit. f GDPR also lies in these purposes.

    4. Duration of storage

      The data will be deleted as soon as they are no longer necessary to achieve the purpose for which they were collected. In the case of the collection of data for the provision of the website, this is the case when the respective session has ended.
      If the data is stored in log files, this is the case after seven days at the latest. Further storage is possible. In this case, the IP addresses of the users are deleted or alienated so that an assignment of the calling client is no longer possible.

    5. Possibility of opt-out and deletion

      The collection of data for the provision of the website and the storage of data in log files is absolutely necessary for the operation of the website. Consequently, there is no possibility of objection on the part of the user.

    1. Description and scope of data processing

      Our website uses cookies. Cookies are text files that are stored in the Internet browser or by the Internet browser on the user's computer system.

      1. Entered search terms
      2. Frequency of page views
      3. Use of website functions


      The user data collected in this way is pseudonymised by technical precautions. Therefore, it is no longer possible to assign the data to the calling user. The data will not be stored together with other personal data of the users.

      We need cookies for the following applications:

      1. Registration
      2. Calling up your own user account
      3. Accepting language settings
      4. Remembering search terms


      The user data collected by technically necessary cookies are not used to create user profiles. The analysis cookies are used to improve the quality of our website and its content. Through the analysis cookies we learn how the website is used and can thus continuously optimize our offer.
      For these purposes, our legitimate interest also lies in the processing of personal data pursuant to Art. 6 para. 1 lit. f GDPR.

    4. Duration of storage, Possibility of opt-out and deletion

  7. Registration
    1. Description and scope of data processing

      For the use of certain functions (user-controlled acquisition of printed publications, access to e-books and/or journals licensed specifically for the subject information service, storage of search queries and/or favorites) of adlr.link, prior registration is required.
      On our website, we offer users the opportunity to register for their own user account by entering personal data. The data is entered into an input mask and transmitted to us and saved. The following data is collected during the registration process:

      1. E-mail address (also login)
      2. Password (self-defined)
      3. Type of user group
      4. First and last name
      5. Form of address/Academic degree (optional)
      6. Home library
      7. Phone (optional)
      8. Address information (street/no., postcode/city) for a maximum of two addresses

        At the time of registration, the following data is also stored:

      9. The IP address of the user
      10. Date and time of registration


      In the course of the registration process, the user's consent to the processing of this data is obtained.
      The password is not stored for security reasons. For user authentication, a hash value is calculated from the password and only this is stored. A hash value is a unique string that is calculated so that the original password cannot be restored. To be able to authenticate you for later logins, your input is calculated with the same function for later logins and only the two hash values are compared.

    2. Legal basis for data processing

      The legal basis for the processing of data is Art. 6 para. 1 lit. a GDPR if the user has given his consent.
      If the registration serves the fulfilment of a contract to which the user is a party or the implementation of pre-contractual measures, the additional legal basis for the processing of the data is Art. 6 para. 1 lit. b GDPR.

    3. Purpose of data processing

      A registration of the user is necessary for the fulfilment of a contract with the user or for the implementation of pre-contractual measures.
      We need your e-mail address in order to communicate with you, to send you the newsletter and to be able to send you documents by electronic means on order. Your e-mail address is also your login (user name) for your user account.
      The password is not stored for security reasons. For user authentication, a hash value is calculated from the password and only this is stored. A hash value is a unique string that is calculated so that the original password cannot be restored. To be able to authenticate you for later logins, your input is calculated with the same function for later logins and only the two hash values are compared.

      We need your name and address information in order to send you printed media by post. You can specify up to two different addresses and indicate at any time to which address we should send the delivery. When you place an order for a printed medium, we pass on your name, the address you have specified as the delivery address and your e-mail address to suppliers and vicarious agents.

      We use your home library to show you whether individual media in your library are either physically available or electronically accessible. We only pass on an identifier for the respective medium (e.g. the ISBN) and an identifier of your home library to a service of the Bibliotheksservice-Zentrum Baden-Württemberg, but no further personal data from you. We use WorldCat services to let you know if individual media are available in a library near you, based on location. To do this, your current IP address and an identifier for each medium (e.g. the ISBN) is transmitted to the WorldCat service. The IP address is only used for the purpose of geotargeting and is not stored or otherwise used. No other personal data will be transmitted.

      You can optionally provide us with additional data in your user account. We use your form of address and academic title for personal addressing and pass this information on together with your address information. We can use your telephone number to answer your questions or place orders over the phone.
      When passing on personal information to third parties, we ensure that the information is provided in accordance with this data protection declaration. Third parties to whom the data are transmitted are obliged to process the data transmitted to them only for the respective purpose, but not to use them beyond that.

    4. Duration of storage

      The data will be deleted as soon as they are no longer necessary to achieve the purpose for which they were collected.
      This is the case for those during the registration process to fulfill a contract or to carry out pre-contractual measures when the data is no longer required for the execution of the contract. Even after conclusion of the contract, it may still be necessary to store personal data of the contractual partner in order to fulfil contractual or legal obligations.

    5. Possibility of opt-out and deletion

      As a user you have the possibility to cancel your registration and your user account at any time. You can change the data stored about you at any time.
      You can change your data yourself at any time via the website.
      For a complete deletion of the data please write us an e-mail or contact us via the contact form.
      If the data is required to fulfil a contract or to carry out pre-contractual measures, premature deletion of the data is only possible insofar as contractual or statutory obligations do not prevent deletion.

  8. Contact form and e-mail contact
    1. Description and scope of data processing

      There is a contact form on our website which can be used for electronic contact. If you take advantage of this option, the data entered in the input mask will be transmitted to us and saved. This data is:

      1. E-mail address
      2. Name
      3. Subject and message content

        At the time the message is sent, the following data is also stored:

      4. The IP address of the user
      5. Date and time of registration


      Your consent is obtained for the processing of the data within the scope of the sending process and reference is made to this data protection declaration.
      Alternatively, you can contact us via the e-mail address provided. In this case, the user's personal data transmitted by e-mail will be stored.
      In this context, the data will not be passed on to third parties. The data is used exclusively for processing the conversation.

    2. Legal basis for data processing

      The legal basis for the processing of data is Art. 6 para. 1 lit. a GDPR if the user has given his consent.
      The legal basis for the processing of data transmitted in the course of sending an e-mail is Art. 6 para. 1 lit. f GDPR. If the e-mail contact is aimed at the conclusion of a contract, the additional legal basis for the processing is Art. 6 para. 1 lit. b GDPR.

    3. Purpose of data processing

      The processing of the personal data from the input mask serves us only for the treatment of the establishment of contact. In the event of contact by e-mail, this also constitutes the necessary legitimate interest in the processing of the data.
      The other personal data processed during the sending process serve to prevent misuse of the contact form and to ensure the security of our information technology systems.

    4. Duration of storage

      The data will be deleted as soon as they are no longer necessary to achieve the purpose for which they were collected. For the personal data from the input mask of the contact form and those sent by e-mail, this is the case when the respective conversation with you has ended. The conversation is terminated when it can be inferred from the circumstances that the facts in question have been finally clarified.
      The additional personal data collected during the sending process will be deleted at the latest after a period of seven days.

    5. Possibility of opt-out and deletion

      You have the possibility to revoke your consent to the processing of personal data at any time. If you contact us by e-mail, you can object to the storage of your personal data at any time. In such a case, the conversation cannot be continued.
      If you have any objections, please send us an e-mail or contact us using the contact form. All personal data stored in the course of contacting us will be deleted in this case.

  9. Web analysis by Matomo
    1. Scope of the processing of personal data

      On our website we use the open source software tool Matomo to analyse the surfing behaviour of our users. The software places a cookie on the user's computer (see above for cookies). If individual pages of our website are accessed, the following data is stored:

      1. Two bytes of the IP address of the user's calling system
      2. The accessed website
      3. The website from which the user has accessed the accessed website (referrer)
      4. The sub-pages accessed from the accessed website
      5. The time spent on the website
      6. The frequency with which the website is accessed


      The software runs exclusively on the servers of our website. The personal data of users is only stored there. The data will not be passed on to third parties.
      The software is set so that the IP addresses are not completely stored, but 2 bytes of the IP address are masked (e.g.: 192.168.X.X). In this way it is no longer possible to assign the shortened IP address to the calling computer.

    2. Legal basis for the processing of personal data

      The legal basis for the processing of users' personal data is Art. 6 para. 1 lit. f GDPR.

    3. Purpose of data processing

      The processing of users' personal data enables us to analyse the surfing behaviour of our users. We are in a position to compile information about the use of the individual components of our website by evaluating the data obtained. This helps us to continuously improve our website and its user-friendliness. For these purposes, it is also in our legitimate interest to process the data in accordance with Art. 6 para. 1 lit. f GDPR. By anonymizing the IP address, the interest of the users in their protection of personal data is sufficiently taken into account.

    4. Duration of storage

      The data will be deleted as soon as they are no longer needed for our recording purposes.

    5. Possibility of opt-out and deletion

      Cookies are stored on the user's computer and transmitted to our site. Therefore, you as a user also have full control over the use of cookies. You can deactivate or restrict the transmission of cookies by changing the settings in your Internet browser. Cookies that have already been saved can be deleted at any time. This can also be done automatically. If cookies are deactivated for our website, it may no longer be possible to use all functions of the website in full.
      We offer our users on this website the possibility of an opt-out from the analysis procedure. In this way, another cookie is placed on your system, which signals to our system not to store the user's data. If the user deletes the corresponding cookie from his own system in store the user's data. If the user deletes the corresponding cookie from his own system in the meantime, he must set the opt-out cookie again.
      More information about the privacy settings of the Matomo software can be found under the following link: https://matomo.org/docs/privacy.
      Here you can switch tracking by Matomo on or off, if this setting is not already automatically controlled by the settings of your browser or an adblocker.

        The right to cancellation does not exist insofar as the processing is necessary

        1. to exercise freedom of expression and information;
        2. for the performance of a legal obligation required for processing under the law of the Union or of the Member States to which the controller is subject or for the performance of a task in the public interest or in the exercise of official authority conferred on the controller;

        5. to assert, exercise or defend legal claims.

    5. Right to information third parties

      If you have exercised your right to have the person in charge correct, delete or limit the processing, he/she is obliged to inform all recipients to whom the personal data concerning you have been disclosed of this correction or deletion of the data or restriction on processing, unless this proves impossible or involves a disproportionate effort.
      You have the right to the person in charge to be informed of these recipients.

    6. Right to data transferability

      You have the right to receive the personal data concerning you that you have provided to the person responsible in a structured, common and machine-readable format. In addition, you have the right to pass this data on to another person in charge without obstruction by the person in charge to whom the personal data was provided, provided that

      1. processing is based on consent pursuant to Art. 6 para. 1 lit. a GDPR or Art. 9 para. 2 lit. a GDPR or on a contract pursuant to Art. 6 para. 1 lit. b GDPR and
      2. processing is carried out by means of automated methods.


      In exercising this right, you also have the right to request that the personal data concerning you be transferred directly from one person in charge to another, insofar as this is technically feasible. The freedoms and rights of other persons must not be affected by this.
      The right to transferability shall not apply to the processing of personal data necessary for the performance of a task in the public interest or in the exercise of official authority conferred on the controller.

    7. Right to objection

      You have the right to object at any time, for reasons arising from your particular situation, to the processing of personal data concerning you under Article 6(1)(e) or (f) of the DSBER; this also applies to profiling based on these provisions.
      The person in charge no longer processes the personal data concerning you, unless he can prove compelling reasons worthy of protection for the processing, which outweigh your interests, rights and freedoms, or the processing serves to assert, exercise or defend legal claims.
      If the personal data concerning you are processed for direct marketing purposes, you have the right to object at any time to the processing of the personal data concerning you for the purpose of such advertising; this also applies to profiling, insofar as it is associated with such direct marketing.
      If you object to the processing for direct marketing purposes, the personal data concerning you will no longer be processed for these purposes.
      You have the possibility to exercise your right of objection in connection with the use of Information Society services, notwithstanding Directive 2002/58/EC, by means of automated procedures using technical specifications.

    8. Right to revoke the data protection declaration of consent

      You have the right to revoke your data protection declaration of consent at any time. The revocation of consent does not affect the legality of the processing carried out on the basis of the consent until revocation.

    9. Automated decision in individual cases including profiling

      You have the right not to be subject to a decision based exclusively on automated processing - including profiling - that has legal effect against you or significantly impairs you in a similar manner. This does not apply if the decision

      1. is necessary for the conclusion or performance of a contract between you and the person responsible,
      2. the legislation of the Union or of the Member States to which the person responsible is subject is admissible and that legislation contains appropriate measures to safeguard your rights, freedoms and legitimate interests; or
      3. with your express consent.
