This service currently displays the most cited English-language original research articles by fields and published in 2006. The main goal of this work is to describe the main characteristics and features of this Google Scholar’s new service, as well as to highlight its main strengths and weaknesses. To do this, a total of 2,515 records were extracted. Additionally, for each record, the following bibliographic data were gathered: broad subject category and subcategory, Title of the document, URL, Authors, Google Scholar Citation profiles’ URL, and Citations received. It is finally concluded that, although the product is easy to use and provides original data about highly cited documents at the level of disciplines, it still suffers of some methodological concerns, mainly related to the subject classification of documents and the use of homogenous visualization threshold regardless the discipline, that jeopardizes the utility of this product for bibliometric purposes. In addition to this, the lack of transparency constitutes a methodological concern, since Google Scholar does not to declare in detail how the product has been developed. Show less

Show moreThe current ways in which documents are made freely accessible in the Web no longer adhere to the models established Budapest/Bethesda/Berlin (BBB) definitions of Open Access (OA). Since those definitions were established, OA-related terminology has expanded, trying to keep up with all the variants of OA publishing that are out there. However, the inconsistent and arbitrary terminology that is being used to refer to these variants are complicating communication about OA-related issues. This study intends to initiate a discussion on this issue, by proposing a conceptual model of OA. Our model features six different dimensions (authoritativeness, user rights, stability, immediacy, peer-review, and cost). Each dimension allows for a range of different options. We believe that by combining the options in these six dimensions, we can arrive at all the current variants of OA, while avoiding ambiguous and/or arbitrary terminology. This model can be an useful tool for funders and policy makers who need to decide exactly which aspects of OA are necessary for each specific scenario. Show less
