search

Search the National Library's catalog - books, newspapers, journals, photos, maps, music, manuscripts, radio/TV and more, both physical and digitized. Digitized text (OCR) is matched too by default, so a query can surface newspaper or book pages that mention a term even when it's not in the title.

Signature: search(q: string, required; media_type: string, optional, default None; language: string, optional, default None; county: string, optional, default None; year_from: integer, optional, default None; year_to: integer, optional, default None; digital_only: yes/no, optional, default False; sort: string, optional, default None; page: integer, optional, default 0; size: integer, optional, default 10; limit: integer, items, optional, default 25; offset: integer, items, optional, default 0)

Direct GET

For navigating agents: open the HTML page with parameters in the URL. The result is fetched and displayed without screenshots or form filling.

Open this validated HTML GET URL

https://allemannsdata.com/wiki/kilder/nasjonalbiblioteket/search/?q={q}&media_type={media_type}&language={language}&county={county}&year_from={year_from}&year_to={year_to}&digital_only=false&sort={sort}&page=0&size=10&limit=25&offset=0

Replace {q}, {media_type}, {language}, {county}, {year_from}, {year_to}, {digital_only}, {sort}, {page}, {size} with values. Remove unused optional parameters from the URL.

For software and dashboards: Read the operation descriptor. The JSON GET template is https://allemannsdata.com/wiki/api/v1/kilder/nasjonalbiblioteket/search?q={q}&media_type={media_type}&language={language}&county={county}&year_from={year_from}&year_to={year_to}&digital_only=false&sort={sort}&page=0&size=10&limit=25&offset=0. Open this exact request as JSON.

Parameter	Requirement	JSON type	Description
`q`	required	string	Free-text query. Supports field-restricted terms too, e.g. "subject:fiske year:1970" combined with free text.
`media_type`	optional	union	Restrict to one type, e.g. aviser (newspapers), bøker (books), tidsskrift (journals), bilder (photos), musikk, kart (maps), film, plakater (posters), noter (sheet music), radio, fjernsyn. See get_aggregations(q="*", group_by="mediatype") for the full list with counts.
`language`	optional	union	Language filter - values are inconsistent in the catalog (mixes codes like "nob" and labels like "Norsk bokmål"); check get_aggregations(q=q, group_by="languages") first if unsure.
`county`	optional	union	Norwegian county name, e.g. "Troms", "Oslo".
`year_from`	optional	union	Restrict to items published/issued in this year range (inclusive).
`year_to`	optional	union	Restrict to items published/issued in this year range (inclusive).
`digital_only`	optional	boolean	Only items that have been digitized.
`sort`	optional	union	One of date, title, otherid, firstDigitalContentTime, optionally suffixed ",desc" (default: relevance).
`page`	optional	integer	Zero-based page index.
`size`	optional	integer	Results per page, 1 to 100 (default 10).
`limit`	optional	integer	Gateway page size; default 25, maximum 100.
`offset`	optional	integer	Number of list items to skip; default 0.

Generated JavaScript, Python and response structure

Use JSON when the user requests code, machine-readable data, value extraction or further computation. Use the HTML GET page to identify the correct source and verify parameters.

Example for generated JavaScript and Python

https://allemannsdata.com/wiki/api/v1/kilder/nasjonalbiblioteket/search?q={q}&media_type={media_type}&language={language}&county={county}&year_from={year_from}&year_to={year_to}&digital_only=false&sort={sort}&page=0&size=10&limit=25&offset=0

Replace URL placeholders and remove unused optional parameters.

JavaScript in a dashboard

const url = "https://allemannsdata.com/wiki/api/v1/kilder/nasjonalbiblioteket/search?q={q}&media_type={media_type}&language={language}&county={county}&year_from={year_from}&year_to={year_to}&digital_only=false&sort={sort}&page=0&size=10&limit=25&offset=0";
const response = await fetch(url);
if (!response.ok) {
  const failure = await response.json();
  throw new Error(`${failure.error.code}: ${failure.error.message} ${failure.suggestion}`);
}
const result = await response.json();
const data = result.data;

Python without additional packages

import json
from urllib.request import urlopen

url = "https://allemannsdata.com/wiki/api/v1/kilder/nasjonalbiblioteket/search?q={q}&media_type={media_type}&language={language}&county={county}&year_from={year_from}&year_to={year_to}&digital_only=false&sort={sort}&page=0&size=10&limit=25&offset=0"
with urlopen(url) as response:
    result = json.load(response)
data = result["data"]

Response structure

{
  "source": "nasjonalbiblioteket",
  "operation": "search",
  "parameters": {},
  "data": {},
  "entities": [],
  "_meta": {"retrieved_at": "...", "sources": [], "cache": {}},
  "_links": {"self": "...", "source": "...", "wiki": "...", "feedback": "..."}
}

Form for manual use

The form is a fallback for people and browser agents that cannot open the GET URL directly.

How an AI agent should use this page

Ground rule: Navigate with HTML GET links to keep explanations and relationships. Use the page's JSON alternative only when concrete values must be extracted, compared or computed.

How to use the search lookup

Replace the placeholders in the HTML GET template; remove optional parameters you do not need.
Check types, units, limits and ID formats in the parameter table.
Follow linked results to canonical pages before combining sources.

Misreading to avoid: An empty list means "no results for this lookup". An error message or unavailable source does not mean the data does not exist.

Source-specific next step

Go to the source page for other operations. Use the JSON template only after the HTML result shows that the parameters and source are correct.
