OA作为新世纪兴起的学术期刊交流和出版模式,日益得到学术界、出版界和图书情报界的重视.DOAJ是目前全球最有影响力的开放存取期刊目录,收录全球LIS期刊146种,这些期刊具有分布范围广、出版语种多、收录时间长、内容质量高等特点,我国台湾地区有6种期刊被收录,大陆地区64种期刊没有1种参加DOAJ.随着OA理念的深入与发展,国内LIS期刊认同OA出版的会逐渐增多. 相似文献

开放存取（OA）期刊作为一种新的学术交流模式,为科研人员获取科研信息提供了新渠道,但仍有不少科研人员对OA期刊持有保留、怀疑、甚至反对的态度,主要原因在于不信任OA期刊的质量。通过以DOAJ收录的0A期刊作为研究对象,分析OA期刊的总体质量,并且从多个方面对SCI收录的OA期刊进行了深入分析与评价。研究表明OA期刊质量已经超越了学术期刊的平均水平,建议重视OA期刊,充分利用OA期刊,使其成为现有馆藏资源的重要补充。 相似文献

Researchers applauded Directory of Open Access Journals (DOAJ)’s new selection criteria that removed many existing journals from its index because they are ‘Not Adhering to Best Practice’. However, many of these journals have acceptable scholarly quality. The present study compares such removed journals to a trustworthy bibliometric database, SCImago Journal & Country Rank (the Scopus Database). It finds many overlaps. Some of the overlapping journals have a high score in the SCImago ranks. This paper calls for a more transparent process of journal reviews by DOAJ or even a re‐examination of the selection criteria and/or the evaluation process. 相似文献

This study examines the payment policies of a list of standalone predatory open access journals available on scholarlyoa.com . It is found that 72% do charge article publication fees (APCs), which is a higher percentage than found in DOAJ journals. The mean number of articles published during 2013 was 227, but ranged from 4 to 2,286 articles. The majority of journals charge low APCs and can be assumed to have modest annual incomes. There was no correlation between the amount of APC charged and the number of articles published. Comparing the number of journals charging APCs compared to the percentage from DOAJ, the findings suggest a connection between predatory practices and charging author fees. However, a comprehensive assessment of the dynamics of open access journal publishing beyond author charges should be done to avoid using APCs alone as a measure of whether a journal is predatory or not. 相似文献

This study aims to present a quantitative analysis of open access (OA) journals in the field of medicine indexed in the Directory of Open Access Journals (DOAJ). The bibliographic data for this study was extracted from DOAJ and inserted into an Excel sheet for analysis. The retrieved data was analyzed by using different quantitative techniques to disclose the findings. The findings disclosed that 3627 OA journals related to the field of medicine are indexed in DOAJ, which represents a substantial increase from just 8 in 2002. Moreover, most of the medical journals (n = 1874 or 51.7%) do not charge any Author Processing Charges (APC) from the authors. The United Kingdom leads the world with 878 (24%) open access journal titles, whereas English is the top language of publication with 3149 (86.8%) OA journals in medicine. Elsevier is the leading publisher with 236 (6.5%) journal titles. A majority of the journals (n = 1595 or 44%) follow a double blind, peer-review process. About 2046 (56.4%) journals publish their contents under the Creative Commons (CC BY) licensing model to enable access and use of scholarly content for educational purposes. 相似文献

Not all the journals included in credible indices meet the ethical rules of COPE, DOAJ, OASPA, and WAME, and there may also be trustworthy journals excluded from these indices, which means they cannot be used as whitelists for trustworthy journals. Equally, the many methods suggested to determine trustworthiness are not reliable because they include questionable criteria. The question arises whether valid criteria for identifying an untrustworthy journal can be determined and whether other assessment procedures are necessary. Since 2017, the Masaryk University Campus Library has been developing a suitable evaluation method for journals. A list of 19 criteria based on those originally suggested by Beall, COPE, DOAJ, OASPA, and WAME were reduced to 10 objectively verifiable criteria following two workshops with librarians. An evaluation of 259 biomedical journals using both the list of 19 and then 10 criteria revealed that 74 journals may have been incorrectly assessed as untrustworthy using the longer list. The most common reason for failure to comply was in the provision of sufficient editorial information and declaration of article processing charges. However, our investigation revealed that no criteria can reliably identify predatory journals. Therefore, a complex evaluation is needed combining objectively verifiable criteria with analysis of a journal's content and knowledge of the journal's background. 相似文献

This paper examines the characteristics of 462 open access (OA) journals being published in India under the green, gold and hybrid models. The sample of journals was selected from DOAJ, IndianJournal.com and Open J‐Gate. Journal characteristics were measured in terms of growth, subjects, publishers, and citations under each model. While characteristics such as growth, subject, and publisher have been identified by exploring the journal's website only, the citation count of these journals has been calculated by using Google Scholar and the Indian Citation Index. The gold road is now the most popular form of OA publishing in the subcontinent. There is a great variation in the size of OA journals and in their publishers. One publisher has more than 77 journals, but 264 publishers publish a single journal only. Overall, the OA journal landscape is greatly influenced by a few key publishers and journals. While 43% of journals charge publication fees and the fees vary from as low as US$10 to as high as US$400, the highest impact factor of the gold OA journals has been noted as 0.58. The data presented here suggest that publication fees are not a major barrier to authorship within the fields of computer science, pharmacy, and medicine. 相似文献
