We have encountered cases wherein the Leganto articles do not resolve to the correct article; instead, they link to another article with the same title. After consultation with Ex Libris, this linking error was determined to occur for articles with duplicate titles because the CrossRef DOI enrichment for the linking parsers only uses the title as a match point.

Currently, addressing these errors requires Ex Libris intervention to make an exception for the citation. To prevent these errors in the future without one-off exceptions, we request an expansion of the CrossRef augmentation logic to include the subtitles.
