Using the Sources

The Reference Library connects the League’s publications with identifiable original works. Each record introduces the document’s subject, identifies its publisher and edition, and links to the text. The annotations explain the material in English; the original work remains attributed to its issuer.

Finding the right document

The library is arranged around theory, Chinese development, European social policy and international relations. Subject dossiers bring related records together. A reader examining public services, for example, can move from Healthy China 2030 to the ILO social-protection recommendation and the European Pillar of Social Rights.

Each addresses a different part of the question: a national programme, an international recommendation and a European framework of principles. The record’s document label identifies that role before the reader opens the external source.

Authors, institutions and document types

A political report sets out an institutional or political account. A party constitution governs the organisation concerned. A white paper presents an official account of a field. A statistical communiqué reports observations under defined classifications and periods.

Treaties, recommendations and political declarations also have different functions. The UN Charter is the organisation’s founding treaty; the Helsinki Final Act records political commitments; ILO Recommendation No. 202 provides international guidance on social-protection floors. A precise citation retains these distinctions.

Editions and dates

The date of a work may differ from the date on its current webpage. The Communist Manifesto was first published in 1848; the linked English edition and its online presentation have their own publication history. Lenin’s The State and Revolution was written in 1917 and first published in 1918.

The UN Charter record links the original 1945 registered text and identifies the current UN text separately. Later amendments changed provisions concerning the membership and voting of UN bodies. For a current institutional rule, the consolidated text and amendment history matter.

Translation and quotation

An official English version and an English summary serve different purposes. The library identifies the edition provided by the publisher. A notice announcing a study outline or policy programme is described as a notice, with its scope kept distinct from the complete publication.

A quotation belongs to a particular edition and location. Section titles and paragraph or article numbers often provide a more useful reference than a page number when web and printed editions differ. Original annotations are the League’s own explanatory text.

Statistics and revisions

A statistical reference identifies a measure, unit, reporting period and coverage. An end-of-year stock, an annual flow and a growth rate describe different observations. Preliminary releases can be revised as fuller information becomes available.

The 2025 national economic and social communiqué and the later science and technology expenditure communiqué illustrate why the release date and statistical edition belong with the figure. Reading Official Statistics develops these questions through national accounts, ratios and international comparisons.

Reading across the collection

A source annotation is an introduction to one work. The longer briefings connect several sources around a defined question. The China and Europe dossiers place those questions within the League’s wider field of work.

Broken links, inaccurate attributions and factual errors can be reported through Corrections. Include the record or article, the relevant passage and the supporting original source. Editorial Policy explains attribution and corrections across the collection.
