Overview

ISO 2789:2022 - Information and documentation - International library statistics defines rules for the collection and reporting of library statistics to support international reporting, improve comparability between countries, and encourage good statistical practice in library and information services. The sixth edition (2022) provides standardized definitions, reporting periods, quality considerations and detailed guidance on what to count and how to present library metrics.

Key topics and technical requirements

ISO 2789:2022 covers a comprehensive set of technical topics and measurement requirements, including:

  • Terms and definitions for libraries, services, collections, access/facilities, management, funding/expenditure and library staff to ensure consistent interpretation.
  • Scope of library activities and changes in user behavior (inside and outside premises) relevant to statistics.
  • Data quality and reporting rules: time periods, sampling, estimated data and presentation for stakeholders.
  • Detailed data collection guidance across major metric groups:
    • Services & use: user counts, lending, interlibrary loans, reference queries, copying, mediated electronic delivery, events, physical visits, user training.
    • Digital services: website visits, use of digital resources, mobile services, social network interactions, institutional repositories and databases.
    • Collections: printed materials, manuscripts, microforms, cartographic items, audiovisual, music, ebooks, multimedia and free internet resources.
    • Access & facilities: opening hours, days open, user places, public access workstations, catalogue records and space.
    • Management, funding & expenditure: operating/capital expenditure, income/funding, preservation, digitization.
    • Staffing: total staff, volunteers and classification of staff roles.
  • Guidance on presenting statistics for internal management, external reporting and international comparison.

Practical applications and users

ISO 2789:2022 is practical for organizations that need reliable library statistics, including:

  • Library managers and administrators - for benchmarking, performance measurement and operational planning.
  • National and regional library agencies - to harmonize statistics for national reporting and cross-country comparisons.
  • Academic, public, special and national libraries - to standardize internal reporting and justify funding.
  • Policy makers and funders - to assess impact, allocate resources and set strategic priorities.
  • Researchers and statisticians - who analyze library trends, digital adoption and service usage.

Benefits include improved comparability, more consistent metrics for decision-making, and guidance for collecting quality data on both physical and digital library services.

ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or

Introduction
This document provides guidance to the library and information services community on the collection
and reporting of statistics.
Clauses 3 and 7 form the core of this document. Clause 3 provides definitions for most of the elements
which constitute a library service; these are for statistical purposes only. Clause 7 recommends how
each of these elements should be counted. Users need to consult both clauses for the complete picture.
This document includes definitions and counting procedures for all types of resources and services that
libraries offer to their users.
It is recognized that not all measures specified in this document can be collected by libraries of different
types and sizes. To give greater completeness, several additional measures (important for some sectors
only) are described in Annex A. The aim is to ensure that, where a particular statistic is collected, the
same definitions and methods are used.
Annex B is important for the compilation and publication of national statistics so that they can be truly
comparable between countries and over time.
As the use of digital library services has become a main issue for showing the role and impact of
libraries, Annex C has been added, giving an overview of methods for measuring digital usage.
The strong requirement to describe and publicize library activities can only be satisfied if data
collection in libraries follows the lines of this document. As far as possible, it is advisable that libraries
collect all data named in this document that concern their activities.
Developments in relation to this document will be monitored and additional statistical measures will
be incorporated as needed.
An alphabetical index is given in Annex D.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not

Subcommittee SC 8, Quality — Statistics and performance evaluation.
This sixth edition cancels and replaces the fifth edition (ISO 2789:2013), which has been technically
revised.
The main changes are as follows:
— problems in the practical application of ISO 2789:2013 have been addressed;
— new development in library services have been taken into account.

Introduction
This document provides guidance to the library and information services community on the collection
and reporting of statistics.
Clauses 3 and 7 form the core of this document. Clause 3 provides definitions for most of the elements
which constitute a library service; these are for statistical purposes only. Clause 7 recommends how
each of these elements should be counted. Users need to consult both clauses for the complete picture.
This document includes definitions and counting procedures for all types of resources and services that
libraries offer to their users.
It is recognized that not all measures specified in this document can be collected by libraries of different
types and sizes. To give greater completeness, several additional measures (important for some sectors
only) are described in Annex A. The aim is to ensure that, where a particular statistic is collected, the
same definitions and methods are used.
Annex B is important for the compilation and publication of national statistics so that they can be truly
comparable between countries and over time.
As the use of digital library services has become a main issue for showing the role and impact of
libraries, Annex C has been added, giving an overview of methods for measuring digital usage.
The strong requirement to describe and publicize library activities can only be satisfied if data
collection in libraries follows the lines of this document. As far as possible, it is advisable that libraries
collect all data named in this document that concern their activities.
Developments in relation to this document will be monitored and additional statistical measures will
be incorporated as needed.
An alphabetical index is given in Annex D.

Avant-propos
L'ISO (Organisation internationale de normalisation) est une fédération mondiale d'organismes nationaux
de normalisation (comités membres de l'ISO). L'élaboration des Normes internationales est en général
confiée aux comités techniques de l'ISO. Chaque comité membre intéressé par une étude a le droit de faire
partie du comité technique créé à cet effet. Les organisations internationales, gouvernementales et non
gouvernementales, en liaison avec l'ISO participent également aux travaux. L'ISO collabore étroitement avec
la Commission électrotechnique internationale (IEC) en ce qui concerne la normalisation électrotechnique.
Les procédures utilisées pour élaborer le présent document et celles destinées à sa mise à jour sont
décrites dans les Directives ISO/IEC, Partie 1. Il convient, en particulier, de prendre note des différents
critères d'approbation requis pour les différents types de documents ISO. Le présent document
a été rédigé conformément aux règles de rédaction données dans les Directives ISO/IEC, Partie 2
(voir www.iso.org/directives).
L'attention est attirée sur le fait que certains des éléments du présent document peuvent faire l'objet de
droits de propriété intellectuelle ou de droits analogues. L'ISO ne saurait être tenue pour responsable
de ne pas avoir identifié de tels droits de propriété et averti de leur existence. Les détails concernant les
références aux droits de propriété intellectuelle ou autres droits analogues identifiés lors de l'élaboration du
document sont indiqués dans l'Introduction et/ou dans la liste des déclarations de brevets reçues par l'ISO

Introduction
Le présent document fournit des règles à la communauté des bibliothèques et des services d'information
pour la collecte et la présentation de statistiques.
Les Articles 3 et 7 forment le cœur du présent document. L'Article 3 fournit les définitions de la plupart des
éléments composant le service d'une bibliothèque, ces définitions ne s'appliquent que dans une perspective
statistique. L'Article 7 indique comment il convient de compter chacun des éléments définis. Il est nécessaire
que les usagers consultent les deux articles pour disposer d'une vue complète.
Le présent document comprend les définitions et les procédures de comptage pour tous les types de
ressources et de services que les bibliothèques proposent à leurs usagers.
Il va sans dire que l'ensemble des données définies dans le présent document ne peuvent être collectées par
des bibliothèques de types ou de tailles différents. À titre de complément, l'Annexe A décrit des données
supplémentaires (qui n'ont d'importance que dans certains cas uniquement). L'objectif visé est de garantir
que lorsque l'on collecte une donnée statistique particulière, on utilise toujours les mêmes définitions et les
mêmes méthodes.
L'Annexe B est importante pour recueillir et publier des statistiques nationales qui soient véritablement
comparables entre les pays et dans le temps.
Étant donné que l'utilisation des services numériques de bibliothèque constitue un enjeu important pour
démontrer le rôle et l'impact des bibliothèques, l'Annexe C a été ajoutée pour fournir un aperçu des méthodes
de mesure des usages numériques.
On ne peut satisfaire la forte demande de description et de diffusion de l'activité des bibliothèques que si
la collecte des données dans les bibliothèques suit les lignes du présent document. Autant que possible, il
est recommandé que les bibliothèques collectent toutes les données de leur activité citées dans le présent
document.
Les développements en rapport avec le présent document seront supervisés et de nouvelles mesures
statistiques seront incorporées en fonction des besoins.
Un index est donné à l'Annexe D.
