Trove newspaper & gazette harvester

The Trove Newspaper & Gazette Harvester makes it easy to download large quantities of digitised articles from Trove's newspapers and gazettes. Just give it a search from the Trove web interface, and the harvester will save the metadata of all the articles in a CSV (spreadsheet) file for further analysis. You can also save the full text of every article, as well as copies of the articles as JPG images, and even PDFs. While the web interface will only show you the first 2,000 results matching your search, the Newspaper & Gazette Harvester will get everything.

You can install the Harvester as a Python command line tool, or use it in one of these notebooks below:

Both notebooks can be run live, online using the Binder service, so you can start harvesting articles straight away without installing any software. All you need to get started is:

Your harvested data

When you start a new harvest, the harvester looks for a directory called data. Within this directory it creates another directory for your harvest. The name of this directory will be in the form of a unix timestamp – a very large number that represents the number of seconds since 1 January 1970. So this means the directory with the largest number will contain the most recent harvest.

The harvester saves your results inside this directory. There will be at least two files created for each harvest:

  • results.csv – a text file containing the details of all harvested articles
  • metadata.json – a configuration file which stores all the details of the harvest

The results.csv file is a plain text CSV (Comma Separated Values) file. You can open it with any spreadsheet program. The details recorded for each article are:

  • article_id – a unique identifier for the article
  • title – the title of the article
  • newspaper_id – a unique identifier for the newspaper or gazette title (this can be used to retrieve more information or build a link to the web interface)
  • newspaper_title – the name of the newspaper (or gazette)
  • page – page number (of course), but might also indicate the page is part of a supplement or special section
  • date – in ISO format, YYYY-MM-DD
  • category – one of ‘Article’, ‘Advertising’, ‘Detailed lists, results, guides’, ‘Family Notices’, or ‘Literature’
  • words – number of words in the article
  • illustrated – is it illustrated (values are y or n)
  • corrections – number of text corrections
  • snippet – short text sample
  • url – the persistent url for the article
  • page_url – the persistent url of the page on which the article is published

If you’ve asked for PDFs or text files, there will be additional directories containing those files. Files containing the OCRd text of the articles will be saved in a directory named text. These are just plain text files, stripped on any HTML. These files include some basic metadata in their file titles – the date of the article, the id number of the newspaper, and the id number of the article. So, for example, the filename 19460104-1002-206680758.txt tells you:

As you can see, you can use the newspaper and article ids to create direct links into Trove:

  • to a newspaper or gazette https://trove.nla.gov.au/newspaper/title/[newspaper id]
  • to an article http://nla.gov.au/nla.news-article[article id]

Similarly, if you've asked for copies of the articles as images, they'll be in a directory named image. The image file names are similar to the text files, but with an extra id number for the page from which the image was extracted. So, for example, the image filename 19250411-460-140772994-11900413.jpg tells you:

Once you have your data you can start exploring! You'll find some Jupyter notebooks below that provide examples of analysing and visualising both the metadata and the full text.

Display the results of a harvest as a searchable database using Datasette

Screen capture of Datasette

Datasette is 'a tool for exploring and publishing data'. Give it a CSV file and it turns it into a fully-searchable database, running in your browser. It supports facets, full-text search, and, with a bit of tweaking, can even present images. Although Datasette is a command-line tool, we can run from within a Jupyter notebook, and open a new window to display the results. This notebook shows you how to load the newspaper data you've harvested into Datasette, and start it up. If you've also harvested full-text and images from the newspaper articles, you can add these to your database as well!

Exploring your TroveHarvester data

This notebook shows some ways in which you can analyse and visualise the article metadata you've harvested — show the distribution of articles over time and space; find which newspapers published the most articles. (Under construction)

Exploring harvested text files

This notebook suggests some ways in which you can aggregate and analyse the individual OCRd text files for each article — look at word frequencies ; calculate TF-IDF values. (Under construction)
