A user highlighted that some De Gruyter items, which we should have access to, aren't showing up as directly accessible in search results: https://meta.wikimedia.org/wiki/Talk:Library_Card_platform/Search/Archive_2
De Gruyter has full access to this book, "Changes in the Roman Empire", but searching for it via the search bar doesn't find it. All it finds are reviews of the book, but not the book itself.
We have a large generic De Gruyter holding selected currently, which we hoped would match our "All Packages" collection available in De Gruyter directly. This doesn't seem to be a direct match.
