Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

catalog-collection scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Catalog Collection

Catalog and classify library or archival materials using standard classification systems and descriptive cataloging practices.

When to Use

  • You are organizing a personal, institutional, or community library from scratch
  • You need to assign call numbers and subject headings to new acquisitions
  • You want to create consistent catalog records for findability
  • You are reclassifying a collection that has outgrown its original system
  • You need to establish authority control for authors, series, or subjects

Inputs

  • Required: Materials to catalog (books, serials, media, archival items)
  • Required: Chosen classification system (Dewey Decimal or Library of Congress)
  • Optional: Existing catalog or inventory to integrate with
  • Optional: Subject heading authority (LCSH, Sears, or custom thesaurus)
  • Optional: MARC-compatible cataloging software (Koha, Evergreen, LibraryThing)

Procedure

Step 1: Choose the Classification System

Select a system that matches the collection's size, scope, and audience.

Classification System Comparison:
+----------------------------+-------------------------------+-------------------------------+
| Criterion                  | Dewey Decimal (DDC)           | Library of Congress (LCC)     |
+----------------------------+-------------------------------+-------------------------------+
| Best for                   | Public/school libraries,      | Academic/research libraries,  |
|                            | personal collections <10K     | collections >10K volumes      |
+----------------------------+-------------------------------+-------------------------------+
| Structure                  | 10 main classes (000-999),    | 21 letter classes (A-Z),      |
|                            | decimal subdivision           | alphanumeric subdivision      |
+----------------------------+-------------------------------+-------------------------------+
| Granularity                | Broad at top levels,          | Very specific; designed for   |
|                            | expandable via decimals       | research-level distinction    |
+----------------------------+-------------------------------+-------------------------------+
| Learning curve             | Moderate — intuitive          | Steeper — requires schedules  |
|                            | decimal logic                 | and tables                    |
+----------------------------+-------------------------------+-------------------------------+
| Browsability               | Excellent for general         | Excellent for subject-deep    |
|                            | browsing                      | collections                   |
+----------------------------+-------------------------------+-------------------------------+

Decision Rule:
- Personal or small community library: DDC
- Academic, research, or large institutional: LCC
- Mixed or uncertain: Start with DDC; migrate to LCC if collection exceeds 10K

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
