||In June 2017 Google Scholar launched a new product called Classic Papers. 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.
