Abstract
Purpose –This paper aims to investigate the longitudinal trends of research in the area of institutional
repositories(IR) using bibliometric and text-mining methods.
Design/methodology/approach –The Library and Information Science Abstracts and the Web of
Science citation databases were usedas data sources. A total of 603 articles published in 109 peer-reviewed
journals from 2005 to 2015 were collected and analyzed. The articles wereanalyzed in terms of publication
trends, authorshippatterns and keywords and phrases appearing in the article titles and abstracts.
Findings –The study shows that there has been a notable growth trendin research outputs, along with
more participation and collaboration among institutes and countries. The study also found significant
variability in the topics covered in the literature. In a comparison of the first period of 2005-2010 and the
second period of 2011-2015, new researchthemes and foci, including research data, data management, linked
open data, studentsand student research and an international audience,are observed in the later period.
Originality/value –This paper provides a comprehensive overview of publication, authorship and
research themes in the IR research field. It describes the evolution of the intellectual structure of IR as a
researchfield.

Introduction
Institutional repositories (IRs) debuted in the 1990s when college and university libraries
began to collect electronic documents, digitizecontent in their special collections and make
that content available via the internet. In 1999, the framework for developing interoperable
archives was developed and became the Open Archive Initiative. In 2001 and 2002,
the development of software tools, such as DSpace and EPrints, created open-source
alternatives for IR development, and in 2002 and 2003, public statements on open access,
including the Budapest Open Access Initiative, the Bethesda Statement on Open Access
Publishing and the Berlin Declaration on Open Access, spurred development and
implementation of IRs. In this historical context, IRs emerged as a new strategyand service
to leverage open access to scholarship, disseminate the intellectual output of institutional
