What classification system do you use to organise your (digital) office library these days? In particular categorisation (i.e. folder organisation, as opposed to tagging).
I haven't settled on anything satisfactory for years. Uniclass 2015 is well attuned to building information but not really an office library.
I've toyed with a system called Specification for Discoverable Construction Knowledge (SDCK) but don't like folder structure.
