An accidental posting by Ellen Chapman (of the Archives & Manuscripts Department at the University of Hawaii at Manoa) to the US Archives and Archivists mailing list brightened my morning today. It was a link to an article by Philip O’Leary in the most recent edition of the Annals of Improbable Research about the complexities of indexing Celtic languages. The article is available in PDF format, and is definitely worth reading if you’ve been struggling with creating index terms in English.
