Is scientific literature subject to a sell-by-date? A general methodology to analyze the durability of scientific documents :

“The study of the citation histories and ageing of documents are topics that have been addressed from several perspectives, especially in the analysis of documents with delayed recognition or sleeping beauties. However, there is no general methodology that can be extensively applied for different time periods and/or research fields. In this paper a new methodology for the general analysis of the ageing and durability of scientific papers is presented. This methodology classifies documents into three general types: Delayed documents, which receive the main part of their citations later than normal documents; Flash in the pans, which receive citations immediately after their publication but they are not cited in the long term; and Normal documents, documents with a typical distribution of citations over time. These three types of durability have been analyzed considering the whole population of documents in the Web of Science with at least 5 external citations (i.e. not considering self-citations). Several patterns related to the three types of durability have been found and the potential for further research of the developed methodology is discussed.”

10 years of Malaria Journal: how did Open Access change publication patterns ? :

“Fifteen years ago, most publications were paper-based, accessible only by subscription. By the late 1990s, this ‘traditional’ mode of access to scientific literature was about to change dramatically, as the result of the development of Open Access. This Editorial, written as Malaria Journal reaches its 10th birthday, looks at the impact of the Open Access movement on publication in the field of tropical medicine in general and malaria in particular.”
