The Web of Science offers users within the Max Planck Society a collection of powerful resources for searching, analyzing and managing bibliographic information from all scientific disciplines. It is produced by Thomson Reuters.
The bibliographic Database Chemical Abstract (CA) is one of the largest scientific databases covering a broad field of literature and patents stretching back to 1900. In addition to the chemical literature it covers physics, material science, biochemistry and genetics, as far as the documents are related to substances.
The separate compound file (REGISTRY) provides access to substances, their names, structures, and registry numbers. In addition proteins and nucleic acid data are indexed providing a unique environment for molecular biologists, e.g. for design of target molecules.
1findr by 1science is a comprehensive Abstracting, Indexing and Analytics (AI&A) system for research papers published in peer-reviewed journals in all fields, all languages and from all over the world. 1findr was designed from the ground up to around a modern link-resolver, oaFindr, which finds free versions of articles, thus providing incredible value compared to traditional AI&A systems. Results can be limited to OA publications by "Access Type".
E-Print ArXiv is a fully automated electronic archive and distribution server for research papers. It covers areas such as physics and related disciplines, mathematics, nonlinear sciences, and computer science.
Faculty of 1000 recommends the most interesting articles published in the biomedical sciences, based on the recommendations of a faculty of 5,000 of the world's leading scientists and clinical researchers (called "Faculty Members"), plus 5,000 associates who work with them (called "Associate Faculty Members"). Faculty of 1000 now comprises four services: F1000Prime, F1000Posters, F1000Research and F1000Trials.
Originally containing digitized back issues of academic journals, it now also includes books and primary sources, and current issues of journals. It provides full-text searches of almost 2,000 journals.
