Danish Heritage Institution Data (Libraries + Archives)
Overview
This directory contains complete datasets for Danish heritage institutions:
- ✅ Libraries: 568 institutions with ISIL codes (DK-XXXXXX format)
- ✅ Archives: 594 institutions WITHOUT ISIL codes (municipal + special collections)
CRITICAL FINDING: Danish ISIL codes (DK-*) are ONLY for libraries, NOT archives.
Danish archives use a completely separate system without international ISIL codes.

Coverage
Total unique institutions: 568 (109 public + 459 research) Total service locations: 1,326 (639 public + 687 research)
This dataset covers:
- ✅ Public libraries (folkebiblioteker)
- ✅ Research libraries (forskningsbiblioteker) including:
- National Library (Det Kgl. Bibliotek)
- University libraries
- Special libraries
- Professional college libraries
- Conservatory libraries
- Various institutional libraries
Data Encoding
- Format: CSV with semicolon (;) delimiter
- Character encoding: UTF-8 with BOM
- Fields enclosed in double quotes
ISIL Code Format
Danish library numbers in this dataset follow the format: 6-digit numbers (e.g., "710100")
These numbers are used in the Danish ISIL codes with prefix DK-X where X is this number.
Next Steps for Data Processing
- Parse CSV files with proper UTF-8-BOM encoding
- Extract ISIL codes (convert library numbers to DK-XXXXXX format)
- Geocode addresses using Nominatim
- Map to LinkML HeritageCustodian schema:
- institution_type: LIBRARY
- data_source: CSV_REGISTRY
- data_tier: TIER_1_AUTHORITATIVE
- Cross-reference with international ISIL registry if needed
- Export to RDF/JSON-LD
Notes on Library Data
- Some entries have empty address fields (branches without physical locations)
- Main library files include leadership information
- Branch files link to parent institutions via Væsensnavn
- Includes some German locations (Sydslesvig/South Schleswig Danish minority libraries)
Archives Data
Source
Data scraped from Arkiv.dk Municipal Archive Directory
- URL: https://arkiv.dk/arkiver
- Operator: Kulturministeriet (Danish Ministry of Culture)
- Date scraped: 2025-11-19
- Method: Browser automation (Playwright + JavaScript evaluation)
Files
- danish_archives_arkivdk.csv - Complete archive list (594 institutions)
- danish_archives_arkivdk.json - Same data with extraction metadata
Data Structure
Columns (CSV):
- municipality - Danish municipality name (e.g., "Albertslund Kommune") or "Specialsamlinger"
- archive_name - Archive institution name
- country - Always "DK"
- source - Always "Arkiv.dk"
- url - Always "https://arkiv.dk/arkiver"
Coverage
Total archives: 594 institutions
Breakdown:
-
Municipal archives: 565 local archives (lokalarkiver)
- Organized by 98 Danish municipalities
- Most municipalities have multiple local archives (one per parish/community)
- ~11 municipalities do NOT contribute to Arkiv.dk (marked "Ingen")
-
Special collections: 29 national/specialized archives
- Includes Rigsarkivet (National Archives of Denmark)
- Provincial archives
- Subject-specific archives (sports, deaf history, prison history, etc.)
- Museum archives
- Religious archives (Freemason lodge, Catholic Historical Archive)
Notable Archives
National Archives:
- Rigsarkivet (National Archives)
Major Municipal Archives:
- Copenhagen (Københavns Kommune): No local archive listed (uses Rigsarkivet)
- Aarhus Kommune: 22 local archives
- Esbjerg Kommune: 23 local archives
- Ringkøbing-Skjern Kommune: 22 local archives
Special Collections Examples:
- Arkivet ved Dansk Centralbibliotek for Sydslesvig (German minority archive)
- Historisk Samling fra Besættelsestiden 1940-1945 (WWII Occupation Historical Collection)
- Niels Bohr Arkivet (Niels Bohr Archive)
- Katolsk Historisk Arkiv (Catholic Historical Archive)
- Friskolearkivet (Free School Archive)
- SIFA Idrætshistorisk Samling (Sports History Collection)
IMPORTANT: No ISIL Codes for Danish Archives
Danish archives do NOT have ISIL codes.
Evidence:
- Official Danish ISIL registry at slks.dk lists ONLY libraries
- The ISIL page redirects to VIP-basen (library database)
- Page title: "Biblioteker i Danmark med biblioteksnumre" (Libraries in Denmark with library numbers)
- Arkiv.dk archive directory does NOT mention ISIL codes
- International ISIL database has no Danish archive entries
This is different from many other countries where archives DO receive ISIL codes.
Scraper Implementation
Script: /scripts/scrapers/scrape_danish_archives_playwright.py
Version: 2.0.0-playwright-js-eval
Technical Details:
- Uses Playwright headless browser automation
- JavaScript evaluation to extract data from collapsed panels (no clicking needed)
- Handles dynamic React/Vue.js content
- Processes municipalities with multiple local archives (newline-separated)
- Separates Specialsamlinger into individual archive records
- Runs in ~5 seconds (much faster than clicking approach)
DOM Structure:
- Municipality tabs:
<h4 class="panel-title"><a data-toggle="collapse" href="#collapseX"> - Archive names: Inside
<div id="collapseX" role="tabpanel"> - Special case: "Ingen" = Municipality does not contribute
Data Quality
- Completeness: 100% coverage of Arkiv.dk directory (all 98 municipalities + special collections)
- Accuracy: Archive names extracted directly from official portal
- Currency: Data current as of 2025-11-19
- Validation: Verified against manual browser inspection
Next Steps for Data Processing
- Parse CSV/JSON files
- Geocode municipality → city location (most archives don't have full addresses)
- Map to LinkML HeritageCustodian schema:
- institution_type: ARCHIVE
- data_source: WEB_SCRAPING (Arkiv.dk)
- data_tier: TIER_2_VERIFIED (official portal)
- NO ISIL codes (field should be empty/null)
- Generate GHCID identifiers (since no ISIL codes available)
- Cross-reference with Rigsarkivet for national/provincial archive details
- Export to RDF/JSON-LD
Notes on Archive Data
- Municipality names: All end with "Kommune" (except Specialsamlinger)
- Local archives: Often named "Lokalhistorisk Arkiv" or "Lokalarkiv"
- Multiple archives per municipality: Common for larger municipalities (Aarhus, Esbjerg, etc.)
- Copenhagen: Does NOT have a local archive listed (uses national archives)
- Specialsamlinger: Includes Rigsarkivet and 28 other specialized archives
- No contact information: Archive names only, no addresses/emails/phones (would need to scrape individual archive pages)
