At OR 2024 I presented on work I had undertaken to add sustainable development goals (SDGs) to EPrints. The goal of this work was to a) present SDGs in an accessible and attractive way in EPrints repositories and b) relieve burden on repository administrators by incorporating automated identification of outputs related to SDGs. This talk will discuss the progress towards this, more specifically an issue that arose of excessive and imprecise identifications by the automated searches that resulted from this search. Comparing the results of these searches in EPrints to those identified by the same search terms in Scopus, I will explore some of the possible reasons for these issues and some of the possible solutions. One specific area of investigation concerns the specific search engine and whether switching to a different mode of searching might alleviate this issue.
