Trove newspapers: data dashboard¶

Trove's collection of digitised newspapers is always changing – new articles and newspapers are being added by the NLA, while Trove users are busy correcting OCRd text and adding tags and comments. The search you run today might produce different results than the same query did a month ago, a year ago, or ten years ago. Researchers need to understand how these changes affect the queries they make, the results they find, and the arguments they construct. This dashboard helps researchers understand the context of their queries by presenting a snapshot of Trove's digitised newspapers, based on weekly data harvests. It shows Trove's current make up from a number of angles, as well as highlighting recent changes. It is updated every Sunday. To explore past changes, see the dashboard archive.

Total articles by publication state¶

Data about the number of articles by publication place (state) is available both from the main result API using the state facet, and from the newspaper API. As noted under Significant events, these totals don't always agree. I've included both below, so you can compare.

Significant events¶

While the changes documented here generally reflect the addition of new articles and newspapers, the total numbers can also be affected by system configuration and optimisation events, such as rebuilding the index. It's difficult to highlight these sorts of anomalies in the charts above, but where I notice them I'll add a note here.

31 May 2022 – reindex?¶

Between the harvests on 29 May and 5 June 2022 there was a dramatic change in the distribution of articles by state (using the state facet). The number of articles from NSW decreased by 939,065, and the number of articles from Victoria increased by 961,387. There were also some smaller changes affecting other states. There was a scheduled maintenance window on 31 May, which makes me think that these reflect changes in the underlying search index, rather than the actual number of articles. Further evidence for this is the fact that the number of articles per state calculated by using the newspaper API endpoint were out-of-sync with the article totals until the end of May. Since then, both sets of article totals have remained in sync. So, in short, the number of articles returned by the state facet between 19 April 2022 (when my harvests started) and 31 May 2022 can't be trusted.
