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.

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

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.

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.

The purpose of this paper is to analyze the file formats of the digital objects stored in two of the largest open-access repositories in Spain, DDUB and TDX, and determines the implications of these formats for long-term preservation, focussing in particular on the different versions of PDF.

To be able to study the two repositories, the authors harvested all the files corresponding to every digital object and some of their associated metadata using the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) and Open Archives Initiative Object Reuse and Exchange (OAI-ORE) protocols. The file formats were analyzed with DROID software and some additional tools.

The results show that there is no alignment between the preservation policies declared by institutions, the technical tools available, and the actual stored files.

The results show that file controls currently applied to institutional repositories do not suffice to grant their stated mission of long-term preservation of scientific literature.

The purpose of this paper is to explain the changes in the Web Content Accessibility Guidelines (WCAG) 2.0 compared with WCAG 1.0 within the context of its historical development.

In order to compare WCAG 2.0 with WCAG 1.0 a diachronic analysis of the evolution of these standards is done. Known authors and publications in the field, the Web Accessibility Initiative (WAI) web pages, WebAIM and the blogosphere were also monitored for comments and third‐party analyses. The analysis of the main changes from WCAG 1.0 to WCAG 2.0 was based on personal experience with WAI guidelines, experimentation with some of the new guidelines, and a selection of best practice online services in the application of the WCAG, including WAI documentation.

WCAG 2.0 is more educational and is applied to more technologies than WCAG 1.0. The limitations of WCAG 1.0 are mostly due to its origin. In changing from one to the other, new priorities and new elements must be taken into account. The paper concludes that though these guidelines are a useful tool for governments, they are only the first step towards accessibility, which can only be achieved through user‐centred design.

This paper explains the significance and limitations of the WCAG and gives a short guide to adapting web sites to the new regulations.

This paper focuses on the use of ISO 9000 standards for the introduction of quality management in information services, with a special emphasis on the Brazilian experience, aiming to provide support to information services managers in the use of quality management.

The research is based on a comprehensive review of the literature, from the earliest citations to those published more recently, principally articles relating to the application of quality programs in Brazilian information services.

The paper presents and discusses the main benefits (ordered according to the eight principles of quality management), the concerns and the difficulties of the use of ISO 9000 mentioned by the analyzed literature.

Although the literature describes several practical experiences and theoretical studies that analyze the application of ISO 9000 in information services, each organization has its own typical characteristics and their internal and external environments may differ, helping or making it more difficult to implement projects related to quality management.

The paper observes a general predisposition towards the principles defined on the ISO 9000 standard series, which can be used as a parameter to guide and support quality improvement initiatives.

The research supports the idea that ISO 9000 standards are a guideline for the implementation of quality management in organizations of different types and sizes. The exponential growth on the number of ISO 9000 certificates in Brazil has created a scenario that has certainly favoured the option of several information services towards the ISO 9000 standard series.
