Publications en libre accès en biologie–médecine : historique et état des lieux en 2016

Posté le par

Auteurs/Authors : Christophe Boudry, Manuel Durand-Barthez

L’apparition du mouvement « open access » (libre accès, LA) et des archives ouvertes a bouleversé (et bouleverse encore) l’économie et l’accès aux publications scientifiques. L’objectif de cet article est de réactualiser et compléter les résultats des études antérieures qui ont tenté de quantifier l’importance du LA dans le domaine de la biologie/médecine, par le biais d’un focus sur la base de données bibliographiques PubMed.

Une analyse des publications en LA dans PubMed en fonction de l’origine géographique des auteurs a également été menée (pays et continents) et un certain nombre de paramètres liés au LA (évolution du nombre de journaux en LA, nombre de mandats et d’archives ouvertes par pays et continents) ont également été étudiés et mis en perspective. Les résultats mettent en évidence que les pourcentages d’articles dont le texte intégral et disponible en LA ne cessent de progresser et concernent en 2015, 39,1 % des articles disponibles dans PubMed.

L’analyse géographique des 25 pays les plus productifs et des continents montre une grande variabilité concernant le pourcentage d’articles en LA (de 21,9 % pour l’Italie à 42,08 % pour les États-Unis et de 22,80 % pour l’Océanie à 40,84 % pour l’Amérique du Nord).

Par ailleurs, nos données montrent que le nombre de mandats et d’archives ouvertes n’est pas corrélé de manière significative au pourcentage d’articles en LA au niveau national et continental, confirmant ainsi que les politiques publiques successives ou les mandats relatifs au LA n’ont eu qu’une influence, sinon secondaire, du moins inférieure aux attentes.

La mise en place de mandats plus coercitifs parviendra peut-être à obtenir des effets plus significatifs à plus ou moins long terme. L’augmentation régulière du nombre de journaux en LA, concomitante à l’augmentation avérée du nombre de citations des articles en LA, amplifiera certainement encore l’attrait des auteurs pour le LA.

Growth of hybrid open access, 2009–2016

Posté le par

Author : Bo-Christer Björk

Hybrid Open Access is an intermediate form of OA, where authors pay scholarly publishers to make articles freely accessible within journals, in which reading the content otherwise requires a subscription or pay-per-view.

Major scholarly publishers have in recent years started providing the hybrid option for the vast majority of their journals. Since the uptake usually has been low per journal and scattered over thousands of journals, it has been very difficult to obtain an overview of how common hybrid articles are.

This study, using the results of earlier studies as well as a variety of methods, measures the evolution of hybrid OA over time. The number of journals offering the hybrid option has increased from around 2,000 in 2009 to almost 10,000 in 2016.

The number of individual articles has in the same period grown from an estimated 8,000 in 2009 to 45,000 in 2016. The growth in article numbers has clearly increased since 2014, after some major research funders in Europe started to introduce new centralized payment schemes for the article processing charges (APCs).

The State of OA: A large-scale analysis of the prevalence and impact of Open Access articles

Posté le par

Authors : Heather Piwowar, Jason Priem, Vincent Larivière, Juan Pablo Alperin, Lisa Matthias, Bree Norlander, Ashley Farley, Jevin West, Stefanie Haustein

Despite growing interest in Open Access (OA) to scholarly literature, there is an unmet need for large-scale, up-to-date, and reproducible studies assessing the prevalence and characteristics of OA. We address this need using oaDOI, an open online service that determines OA status for 67 million articles.

We use three samples, each of 100,000 articles, to investigate OA in three populations: 1) all journal articles assigned a Crossref DOI, 2) recent journal articles indexed in Web of Science, and 3) articles viewed by users of Unpaywall, an open-source browser extension that lets users find OA articles using oaDOI.

We estimate that at least 28% of the scholarly literature is OA (19M in total) and that this proportion is growing, driven particularly by growth in Gold and Hybrid. The most recent year analyzed (2015) also has the highest percentage of OA (45%). Because of this growth, and the fact that readers disproportionately access newer articles, we find that Unpaywall users encounter OA quite frequently: 47% of articles they view are OA. Notably, the most common mechanism for OA is not Gold, Green, or Hybrid OA, but rather an under-discussed category we dub Bronze: articles made free-to-read on the publisher website, without an explicit Open license.

We also examine the citation impact of OA articles, corroborating the so-called open-access citation advantage: accounting for age and discipline, OA articles receive 18% more citations than average, an effect driven primarily by Green and Hybrid OA. We encourage further research using the free oaDOI service, as a way to inform OA policy and practice.

Open Access and Global Inclusion: A Look at Cuba

Posté le par

Authors : Authors : Elizabeth Jardine, Maureen Garvey, J. Silvia Cho

Is the Open Access movement meeting its goal of equalizing access to research worldwide? What we learned in libraries and archives during a delegation to Cuba inspired us to pursue this question.

Latin America has long used OA to share its research, but it still has not achieved parity in access and contribution with the developed world. We consider what the OA movement can do to relieve some of these global inequities.

Open Access to Scientific Information in Emerging Countries

Posté le par

Author : Joachim Schöpfel

Access to information plays a critical role in supporting development. Open access to scientific information is one solution. Up to now, the open access movement has been most successful in the Western hemisphere.

The demand for open access is great in the developing world as it can contribute to solving problems related to access gaps. Five emerging countries, called BRICS — Brazil, Russia, India, China and South Africa — play a specific and leading role with a significant influence on regional and global affairs because of their large and fast-growing national economies, their demography and geographic situation.

In order to better understand open access in each of the five countries, in this paper we take a look at specific conditions in each country, relying on data from information professionals and scientists from BRICS, with an empirical approach focused on country-specific characteristics and challenges.

E-Journals and the Big Deal: A Review of the Literature

Posté le par

Author : Cindy Sjoberg

Faced with shrinking budgets and increased subscription prices, many academic libraries are seeking ways to reduce the cost of e-journal access. A common target for cuts is the “Big Deal,” or large bundled subscription model, a term coined by Kenneth Frazier in a 2001 paper criticizing the effects of the Big Deal on the academic community.

The purpose of this literature review is to examine issues related to reducing e-journal costs, including criteria for subscription retention or cancellation, decision-making strategies, impacts of cancellations, and other options for e-journal content provision. Commonly used criteria for decision-making include usage statistics, overlap analysis, and input from subject specialists.

The most commonly used strategy for guiding the process and aggregating data is the rubric or decision grid. While the e-journal landscape supports several access models, such as Pay-Per-View, cloud access, and interlibrary loan, the Big Deal continues to dominate. Trends over the past several years point to dwindling support for the Big Deal however, due largely to significant annual rate increases and loss of content control.

Free articles and Accounting for the timing effect

Posté le par

Authors : Nursyeha Binte Yahaya, Tay Chee Hsien Aaron

Various studies have attempted to assess the amount of free full text available on the web and recent work have suggested that we are close to the 50% mark for freely available articles (Archambault et al. 2013; Björk et al. 2010; Jamali and Nabavi 2015).

Our paper contributes to the literature by taking into account the timing issue by studying when the papers were made free. We sampled citations made by researchers who published in 2015 (based on records in the Singapore Management University Institution repository), checked the number of cited papers that were free at the time of the study and then attempted to “carbon date” the freely available papers to determine when they were first made available.

This allows us to estimate the length of time the free cited article was made available before the citing paper was published. We find that in our sample of cited papers in Economics, the median freely available cited paper (oldest variant) was made available 7-8 years before the citing paper was published.

Of these papers found free via Google Scholar, the majority 67% (n=47) was made available via University websites (not including Institutional repositories) and 32.8% (n=23) were final published versions.
