I need to find daily newspapers that are freely available online in the ZDB-Katalog. What specific search parameters (index and value) should I use for 'daily newspapers' and 'freely available online'? Also, does the ZDB-Katalog index individual newspaper articles, or only broader publication types?
Navigate to 'zeitschriftendatenbank.de'. Click on the 'Services' link. Under 'Schnittstellen' (Interfaces), click on the 'Hilfe zur Suche' (Help for searching) link. Locate the 'Indizes' (Indexes) section. Identify the index for 'Erscheinungsfrequenz' (frequency) and its value for daily newspapers. Identify the index for 'online kostenfrei verfügbar' (online freely available) and its value. Determine from the 'Dokumenttyp' (Document type) index or other text whether individual newspaper articles are indexed. Synthesize the identified information to answer the query.
State that daily newspapers can be found using the 'erf' (Erscheinungsfrequenz/frequency) index with 'täglich' (daily) as the value. State that online freely available content can be found using the 'kfr' (online kostenfrei verfügbar/online freely available) index with a value of '1'. Confirm that the ZDB-Katalog does NOT contain individual newspaper articles, but rather indexes publications at a higher level (e.g., 'Zeitschrift', 'Serie', 'Zeitung').
