Do historians doing archival research have any shared norms or habits around nail care?
I've been preparing for archival research on early 20th century Central European documents and went down a rabbit hole on glove protocols. The current consensus apparently favors bare clean hands over cotton gloves for paper, nitrile for photographs.
But this got me wondering about a more mundane adjacent question: do people who do heavy archival work develop any practical habits or informal norms around nail length and nail care?
I'm thinking both from a document-handling standpoint (long nails potentially catching on fragile paper edges, flaking iron gall ink, etc.) and from a contamination standpoint (nail polish, oils).
Has anyone encountered explicit guidance on this? Is there any archival science research on the matter? Anecdotal observations from your own experience also welcome.
