Facets

Attention

Not sure where this belongs…

Note that categories do not supply a full list of formats. It seems that they are filtered (particularly in Image, Sound) to only show those that are ‘relevant’. But if you explicitly search for a facet it will pop up in the list of facets, eg: https://trove.nla.gov.au/search/category/images?keyword=&l-format=Book (Book appears in facets) vs https://trove.nla.gov.au/search/category/images?keyword= (Book doesn’t appear in facets)

Facet numbers don’t add up – relationship between parents and children complex. This is formats from Book category:

The Book parent contains more than it’s children (which is what you’d expect), but ‘Article’ parent contains fewer. Why?

Magazines and newsletters:

• difference between title and contribCollection facets

contribcollection – search for things like “ABC Radio National. RN Breakfast” from inpartof don’t seem to work, need to use contribcollection facet instead
