Purpose

This paper aims to carry out a literature review on the implementation of digital preservation policies, strategies and actions by institutional repositories. The objective is to identify, out of the published experiences, at which level they are fulfilling the function of ensuring the long-term availability of the deposited materials.

Design/methodology/approach

Using a systematic literature review methodology, a total of 21 articles from international refereed journals published between 2009 and 2020 are reviewed.

Findings

The research production on this subject is very limited. The scarce number of published articles proves that the interest of repository managers has been focused on issues other than to assure the long-term availability of the assets they store. The literature review has not found clear evidence about how institutional repositories are implementing digital preservation. It is particularly striking the lack of works focused on the situation in European countries. More field studies are needed. They would allow to extract conclusions and produce best practices to help managers to improve preservation strategies.

Originality/value

This study has shown that one of the main functions of repositories is not being dealt with as promised by repository managers. More work in this area is needed. In particular, it is necessary for a study at the European level to gather detailed data that will allow to draw a portrait of the current situation, extract conclusions and produce best practices to help managers to improve or develop preservation strategies.

机构存储库中的数字保存：系统文献回顾

目的

本文旨在对机构存储库实施数字保存政策、战略和行动进行文献综述。目的是从已发表的经验中确定它们在哪个级别上履行了确保沉积材料的长期可用性的功能。

设计/方法/方法

使用系统的文献综述方法，对 2009 年至 2020 年间发表的国际参考期刊的 21 篇文章进行了综述。

发现

这方面的研究成果非常有限。发表的文章数量稀少证明存储库管理人员的兴趣一直集中在其他问题上，而不是确保他们存储的资产的长期可用性。文献回顾没有找到关于机构存储库如何实施数字保存的明确证据。尤其引人注目的是缺乏关注欧洲国家情况的作品。需要更多的实地研究。他们将允许提取结论并产生最佳实践，以帮助管理人员改进保存策略。

原创性/价值

这项研究表明，存储库的主要功能之一没有得到存储库管理器的承诺。需要在这方面开展更多工作。特别是，有必要在欧洲层面进行一项研究，以收集详细的数据，以便描绘当前情况、得出结论并产生最佳实践，以帮助管理人员改进或制定保存策略。
