Abstracting and Indexing

Google Scholar is a freely accessible web search engine that indexes the full text or metadata of scholarly literature across an array of publishing formats and disciplines. Released in beta in November 2004, the Google Scholar index includes most peer-reviewed online academic journals and books, conference papers, theses and dissertations, preprints, abstracts, technical reports, and other scholarly literature, including court opinions and patents. While Google does not publish the size of Google Scholar's database, third-party researchers estimated it to contain roughly 160 million documents as of May 2014[2] and an earlier statistical estimate published in PLOS ONE using a Mark and recapture method estimated approximately 80-90% coverage of all articles published in English with an estimate of 100 million.


BASE is one of the world's most voluminous search engines especially for academic web resources. BASE provides more than 150 million documents from more than 7,000 sources. You can access the full texts of about 60% of the indexed documents for free (Open Access). BASE is operated by Bielefeld University Library. We are indexing the metadata of all kinds of academically relevant resources – journals, institutional repositories, digital collections etc. – which provide an OAI interface and use OAI-PMH for providing their contents (see our Golden Rules for Repository Managers). The index is continuously enhanced by integrating further sources (you can suggest a source which is not indexed yet). We are working on several new features like a claiming service for authors within the ORCID DE project. BASE is a registered OAI service provider. Database managers can integrate the BASE index into their local infrastructure (e.g. meta search engines, library catalogues). Further on there are several tools and services for users, database and repository managers. In comparison to commercial search engines, BASE is charcterised by the following features: Sources are indexed only after check by qualified personnel of Bielefeld University Library


The first step in systemic implementation of scientific achievements to the socioeconomic environment is the parameterisation of scientific achievements. The parametrisation carried out by Index Copernicus aims to describe the achievements in a unified and comprehensible form with the use of specific metadata structure. Parametrised (described) scientific achievements can be assessed then (assessment involving the translation of the description of the given scientific achievement to point values in accordance with the adapted convention). The scientific databases of Index Copernicus include and parametrise data related to scientific journals, research units as well as the scientists and their achievements. The IT systems used to evaluate science support processing of specific metadata on "evaluation events" – unitary activities characteristic for the science as the segment of the economy. In parametrisation we use the most promising achievements of bibliometrics or - more widely - scientometrics.

Academic Business Current Data (ABCD) index is a free to access platform for scholars, researchers, publishers, colleges, universities. This platform provides a systematic search with filters for international journals, publishers, research papers. Platform was developed with the thought that researchers need a single platform that can provide genuine information of all types of journals with related indexing details. As some people are running journals which are not doing their work regularly, some journals have good indexing but have less attentive team to respond. So this portal works in two different dimensions, first for journal information and other for published papers.
