Loose-sheet supports — Comparison and alternatives
An enclosure for loose sheets should distinguish the stack, support and access margin. Handling needs differ from those of a bound volume.
Scope and purpose
Compare alternatives using the same question and context. A difference in wording, layout or scale is not automatically a difference in performance. Keep the original observations available and explain which differences are meaningful for this comparison.
Working notes
This collection describes enclosure forms, access routes and documentation practices for paper-based material. It is intended for reading and planning, not for directing treatment of fragile objects. Fold diagrams and record examples are original illustrations with no associated collection or accession data. Material descriptions distinguish observed features from documented properties. Decisions about a real object, its condition and its environment require the relevant professional judgement.
Practical example
Show the support edge and the preferred lifting region outside the image area.

Review checklist
State the comparison question; align context and labels; list common features separately from differences; leave unsupported conclusions open.
