TIANLICHUJU — PERSONAL VERIFICATION WORKSHEET
A Hallway Library without a Bottleneck
https://tianlichuju.com/journal/a-hallway-library-without-a-bottleneck/

PROPOSED CHECKS — NO MEASURED RESULTS SUPPLIED
Date: __________________  Units: __________________
Room / product reference: __________________

1. Collection depth
Where: At the books that would actually move into the hallway.
Record: Measure representative depths and heights in centimeters or inches, separating oversized volumes; record the proposed shelf projection including book spines.
Your observation: ______________________________________________
Interpretation: The deepest book need not determine every hallway shelf when those volumes have a better home elsewhere.
Alternative: Reduce the hallway collection or retain large books in a suitable room cabinet.

2. Occupied passage
Where: At the narrowest shelf location with nearby doors fully operated.
Record: Sketch handles, switches and door arcs; record remaining width with units and note conflicts while residents carry ordinary laundry or bags.
Your observation: ______________________________________________
Interpretation: The library remains optional; suitable movement and applicable escape-route requirements cannot be traded for another shelf.
Alternative: Shorten the run, reduce appropriate depth or abandon hallway shelving where circulation fails.

3. Shelf support and retrieval
Where: At each proposed shelf span and its actual wall or furniture support.
Record: List intended book loads and product capacity information; note wall construction, fixing proposal and which volumes require awkward reaching.
Your observation: ______________________________________________
Interpretation: A decorative shelf appearance is not evidence of suitable load support or comfortable access.
Alternative: Specify a suitable supported system and relocate heavy or inaccessible books before installation.

PRACTICAL TRIAL
1. Represent the projection temporarily with stable empty boxes, then remove them promptly after testing the route and doors.
2. Ask the supplier or installer to relate capacity and fixing information to the actual shelf arrangement and wall.
3. Choose and return a book under evening lighting without reaching across obstacles or relying on improvised climbing.

COMPARE THE SAME SCOPE
- Short shallow standard units where they fit appropriately
- Fitted runs with verified support and clear access
- A smaller hallway selection with reserve books elsewhere
Cost drivers: Shelf strength, spans and appropriate anchoring; Irregular wall fitting and finished exposed ends; Useful passage lighting and any separate collection storage
Choose another route when: Do not install a hallway library where suitable circulation, required access or safely supported book loads cannot remain.

EVIDENCE BOUNDARY
Measurements and trials document a proposed layout; they do not establish building compliance or substitute for a load-rated specification.

DECISION CONDITIONS
choose: Choose a hallway library when the genuinely generous sections can hold the actual books on suitable shelving without obstructing doors, controls or daily passage.
alternative: If a continuous run narrows the corners, use shorter shelf sections or move part of the collection into an occupied room rather than assuming every wall needs matching storage.
stop: Do not commission shelving before its book load, fixing requirements and installation substrate are resolved. Shallow depth and a calm elevation do not establish structural suitability or a safe route.

US CPSC: Anchor It
https://www.cpsc.gov/Safety-Education/Safety-Education-Centers/AnchorItgov
CPSC’s Anchor It guidance calls for furniture to be secured according to manufacturer instructions to reduce tip-over risk. A hallway book-storage proposal therefore needs a restraint plan as well as an attractive elevation; adding heavy books does not prove that a tall freestanding unit is stable.
Scope: This is tip-over guidance, not a shelf-span calculation or approval of a bespoke bookcase, fixing substrate or passage width in a particular home.
