To articulate the interpretations and adaptations of Grounded Theory made within the 2G method, and the motivations behind them.

Literature review and conceptual approach reflecting on the authors' experience of having developed the 2G method.

Identifies six adaptations of Grounded Theory as being of particular interest. Five relate to method procedures, namely: developing a core category; coding interview data; exposing evolving theories to stakeholders; developing multiple concept frameworks; and inter‐linking concepts. The sixth relates to expectations on method users, and the tension between expertise relating to the phenomenon being analysed, and openness in interpreting the data.

Shows how Grounded Theory procedures have been adapted and used in IS methods. Specifically, the paper illustrates and makes explicit how a specific method (the 2G method) has evolved.

Provides insights for users of Grounded Theory (GT) and developers of IS methods on how GT procedures have been interpreted and adapted in previous and the authors' own research.

Provides insights into how Grounded Theory (GT) procedures have been adapted for use in other IS methods, with insights from the authors' own experience of having developed the 2G method. Reflects on the use of GT procedures in a number of case studies related to tool evaluation. Identifies six areas in which specific interpretations or adaptations of GT were considered necessary in the contexts in which the studies were undertaken, and justifies these six departures from standard interpretations of GT procedures.

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.
