List of academic databases and search engines Wikipedia list article This page contains a representative list of notable databases and search engines useful in an academic setting for finding and accessing articles in academic journals, institutional repositories, archives, or other collections of scientific and other articles. Databases and search engines differ substantially in terms of coverage and retrieval qualities. Users need to account for qualities and limitations of databases and search engines, especially those searching systematically for records such as in systematic reviews or meta-analyses. As the distinction between a database and a search engine is unclear for these complex document retrieval systems, see: the general list of search engines for all-purpose search engines that can be used for academic purposesthe article about bibliographic databases for information about databases giving bibliographic information about finding books and journal articles.
Deutsche National Bibliothek "ZEIG DICH" // Museum Night at the German Museum of Books and Writing of the German National Library in Leipzig // Saturday, 6 May 2017, 18:00-24:00 This year's theme is "Zeig dich!" ("Show yourself!") and numerous museums and collections in Halle and Leipzig will be opening their doors to present themselves and their diverse holdings. Yet the theme also invites the Museum Night visitors to have plenty of fun exploring everything that the different museums have to offer. RDFa Distiller and Parser This distiller corresponds to the RDFa 1.0 specification. In 2012, W3C has published an updated version of that specification, called RDFa Core 1.1. A new distiller, processing RDFa 1.1 content, has been implemented which suprecedes this one. Note that the new distiller can also process RDFa 1.0 content (there are some minor incompatibilities) if the XHTML+RDFa file uses the right (RDFa 1.0) DTD and/or the @version attribute. Users are advised to migrate to RDFa 1.1 in general, including the RDFa 1.1 distiller. If you intend to use this service regularly on large scale, consider downloading the package and use it locally.
