The previous search for newspapers from 1900-1910 yielded no results. Please investigate why this might be the case by first changing the sorting order from 'Nově přidané' (Newly added) to 'Podle výskytů' (By occurrences) for the existing 'Noviny a časopisy' (Newspapers and magazines) category with the 1900-1910 filter still active. If this still yields no results, clear the year filters and then identify the earliest and latest publication years available for 'Noviny a časopisy' (Newspapers and magazines) without any year filters applied. Finally, state the title and publication year of the first newspaper listed when sorted by 'Podle výskytů' within the full date range.
Navigate to 'https://kramerius5.nkp.cz/search'. Click on the 'Procházet' (Browse) link. Click on the 'Noviny a časopisy' (Newspapers and magazines) link. In the 'Rok vydání' (Publication year) filter, enter '1900' in the 'Od' (From) field. In the 'Rok vydání' (Publication year) filter, enter '1910' in the 'Do' (To) field. Click the 'Použít' (Apply) button next to the year filter. Click on the 'Řazení: Nově přidané' (Sorting: Newly added) dropdown. Select 'Podle výskytů' (By occurrences) from the sorting options. If results appear, identify the title and publication year of the first newspaper listed. If no results appear after changing sorting, click the 'date_rangeclose' icon next to '1900 - 1910' to clear the year filter. Identify the earliest and latest publication years displayed in the 'Rok vydání' (Publication year) filter fields. Ensure the sorting is still 'Podle výskytů' and identify the title and publication year of the first newspaper listed in the full date range.
The agent successfully changes the sorting to 'Podle výskytů'. If results are found for 1900-1910 after sorting, the agent states the title and publication year of the first result.

The agent correctly identifies the latest publication year available for 'Noviny a časopisy' (e.g., '2025').
