I am a researcher interested in the historical newspaper 'Berliner Tageblatt'. I need to determine if it's available online for free and identify at least one library that holds physical copies. Additionally, I'd like to know if the ZDB-Katalog provides information on the frequency of publication for periodicals in general.
Navigate to the ZDB-Katalog homepage (https://zdb-katalog.de). Enter 'Berliner Tageblatt' into the 'Suche im ZDB-Katalog' search bar (ID 68) and click the submit button (ID 70). On the search results page, locate and apply the filter for 'Online kostenfrei verfügbar' (Online freely available). Examine the filtered results to determine if 'Berliner Tageblatt' is listed as freely available online. Click on a relevant search result for 'Berliner Tageblatt' to view its detailed record. On the detailed record page, identify at least one library listed as holding the newspaper. Review the detailed record or any available filters on the search results page to confirm if publication frequency information is provided for periodicals (e.g., 'Erscheinungsweise' or 'Frequenz'). Synthesize the findings regarding online availability, holding libraries, and publication frequency.
The agent successfully navigates to the ZDB-Katalog homepage and searches for 'Berliner Tageblatt'. The agent successfully applies the 'Online kostenfrei verfügbar' filter. The agent correctly states whether 'Berliner Tageblatt' is listed as freely available online after applying the filter. The agent identifies and states the name of at least one library holding 'Berliner Tageblatt' (e.g., 'Staatsbibliothek zu Berlin - Preußischer Kulturbesitz' or 'Deutsche Nationalbibliothek'). The agent confirms that publication frequency information is available for periodicals, either by identifying a 'Frequenz' filter or finding 'Erscheinungsweise' within a detailed record.
