History
Google Scholar arose out of a discussion between Alex Verstak and Anurag Acharya,[8] both of whom were then working on building Google's main web index.[9][10] Their goal was to "make the world's problem solvers 10% more efficient"[11] by allowing easier and more accurate access to scientific knowledge. This goal is reflected in the Google Scholar's advertising slogan "Stand on the shoulders of giants", which was taken from an idea attributed to Bernard of Chartres, quoted by Isaac Newton, and is a nod to the scholars who have contributed to their fields over the centuries, providing the foundation for new intellectual achievements.[12] One of the sources for the texts in Google Scholar is the University of Michigan's print collection.[6]
Scholars have gained a range of features over time. In 2006, a citation importing feature was implemented supporting
A major enhancement was rolled out in 2012, with the possibility for individual scholars to create personal "Scholar Citations profiles".[16] A feature introduced in November 2013 allows logged-in users to save search results into the "Google Scholar library", a personal collection which the user can search separately and organize by tags.[17] Via the "metrics" button, it reveals the top journals in a field of interest, and the articles generating these journal's impact can also be accessed. A metrics feature now supports viewing the impact of whole fields of science and academic journals.[18]
Features and specifications
Google Scholar allows users to search for digital or physical copies of articles, whether online or in libraries.
Groups and access to literature
Using its "group of" feature, it shows the available links to journal articles. In the 2005 version, this feature provided a link to both subscription-access versions of an article and to free full-text versions of articles; for most of 2006, it provided links to only the publishers' versions. Since December 2006, it has provided links to both published versions and major open access
Citation analysis and tools
Through its "cited by" feature, Google Scholar provides access to abstracts of articles that have cited the article being viewed.
"Scholar Citations profiles" are public author profiles that are editable by authors themselves.
Related articles
Through its "Related articles" feature, Google Scholar presents a list of closely related articles, ranked primarily by how similar these articles are to the original result, but also taking into account the relevance of each paper.[24]
US legal case database
Google Scholar's legal database of US cases is extensive. Users can search and read published opinions of US state appellate and supreme court cases since 1950, US federal district, appellate, tax, and bankruptcy courts since 1923 and US Supreme Court cases since 1791.[23] Google Scholar embeds clickable citation links within the case and the How Cited tab allows lawyers to research prior case law and the subsequent citations to the court decision.[25]

Limitations and criticism
Some searchers found Google Scholar to be of comparable quality and utility to subscription-based databases when looking at citations of articles in some specific journals.
Google Scholar does not publish a list of journals crawled or publishers included, and the frequency of its updates is uncertain. Bibliometric evidence suggests Google Scholar's coverage of the sciences and social sciences is competitive with other academic databases; as of 2017, Scholar's coverage of the arts and humanities has not been investigated empirically and Scholar's utility for disciplines in these fields remains ambiguous.[34] Especially early on, some publishers did not allow Scholar to crawl their journals. Elsevier journals have been included since mid-2007, when Elsevier began to make most of its ScienceDirect content available to Google Scholar and Google's web search.[35] However, a 2014 study[4] estimates that Google Scholar can find almost 90% (approximately 100 million) of all scholarly documents on the Web written in English. Large-scale longitudinal studies have found between 40 and 60 percent of scientific articles are available in full text via Google Scholar links.[36]
Google Scholar puts high weight on citation counts in its ranking algorithm and therefore is being criticized for strengthening the
