MetaLib is a federated search system developed by Ex Libris Group. MetaLib conducts simultaneous searches in multiple, and often heterogeneous, information resources such as library catalogs, journal articles, newspapers and selected quality Internet resources. The resources are often subscription based, and MetaLib provides access for legitimate users. MetaLib is often used in conjunction with the SFX OpenURL resolver. [1]
The Comprehensive Perl Archive Network (CPAN) is a repository of over 250,000 software modules and accompanying documentation for 39,000 distributions, written in the Perl programming language by over 12,000 contributors. CPAN can denote either the archive network or the Perl program that acts as an interface to the network and as an automated software installer. Most software on CPAN is free and open source software.
Internet research is the practice of using Internet information, especially free information on the World Wide Web, or Internet-based resources in research.
A metasearch engine is an online information retrieval tool that uses the data of a web search engine to produce its own results. Metasearch engines take input from a user and immediately query search engines for results. Sufficient data is gathered, ranked, and presented to the users.
The Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) is a protocol developed for harvesting metadata descriptions of records in an archive so that services can be built using metadata from many archives. An implementation of OAI-PMH must support representing metadata in Dublin Core, but may also support additional representations.
Hybrid library is a term used by librarians to describe libraries containing a mix of traditional print library resources and the growing number of electronic resources.
Karlsruher Virtueller Katalog (KVK) is a book search engine administered by the library of the Karlsruhe Institute of Technology. It was developed by KIT-Library in 1996 and continuously expanded and adapted since. It searches a large number of catalogs of research libraries and consortia in Germany, Austria, and Switzerland, as well as important consortia and national library catalogs in other countries. Beyond that it also searches open access and digital media search engines and catalogs. It is said to encompass more than 600 million books and serial publications.
The Internet Encyclopedia of Philosophy (IEP) is a scholarly online encyclopedia, dealing with philosophy, philosophical topics, and philosophers. The IEP combines open access publication with peer reviewed publication of original papers. Contribution is generally by invitation, and contributors are recognized and leading international specialists within their field.
A systematic review is a scholarly synthesis of the evidence on a clearly presented topic using critical methods to identify, define and assess research on the topic. A systematic review extracts and interprets data from published studies on the topic, then analyzes, describes, critically appraises and summarizes interpretations into a refined evidence-based conclusion. For example, a systematic review of randomized controlled trials is a way of summarizing and implementing evidence-based medicine.
Secondary research involves the summary, collation and/or synthesis of existing research. Secondary research is contrasted with primary research in that primary research involves the generation of data, whereas secondary research uses primary research sources as a source of data for analysis. A notable marker of primary research is the inclusion of a "methods" section, where the authors describe how the data was generated.
AARLIN was a successful Australian project to develop "a national virtual research library system that will provide unmediated, personalized and seamless end-user access to the collections and resources of Australian libraries and document delivery services" and the federated search service and consortium that was the project outcome. It ceased operation at the end of 2010.
LibX was a free, open-source scholars' extension for the Internet Explorer browser that lets people use services offered by their library. Users can search their library catalog(s) and databases through a search bar or through a context menu. The context menu is adaptive and configurable. LibX supports the catalogs of all major vendors. In addition, any resource that can be searched using an http GET request can be included, similar to Firefox's smart keywords.
BASE is a multi-disciplinary search engine to scholarly internet resources, created by Bielefeld University Library in Bielefeld, Germany. It is based on free and open-source software such as Apache Solr and VuFind. It harvests OAI metadata from institutional repositories and other academic digital libraries that implement the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH), and then normalizes and indexes the data for searching. In addition to OAI metadata, the library indexes selected web sites and local data collections, all of which can be searched via a single search interface.
A review article is an article that summarizes the current state of understanding on a topic within a certain discipline. A review article is generally considered a secondary source since it may analyze and discuss the method and conclusions in previously published studies. It resembles a survey article or, in news publishing, overview article, which also surveys and summarizes previously published primary and secondary sources, instead of reporting new facts and results. Survey articles are however considered tertiary sources, since they do not provide additional analysis and synthesis of new conclusions. A review of such sources is often referred to as a tertiary review.
A schema crosswalk is a table that shows equivalent elements in more than one database schema. It maps the elements in one schema to the equivalent elements in another.
Metadata is "data that provides information about other data", but not the content of the data itself, such as the text of a message or the image itself. There are many distinct types of metadata, including:
A digital library, also called an online library, an internet library, a digital repository, a library without walls, or a digital collection, is an online database of digital objects that can include text, still images, audio, video, digital documents, or other digital media formats or a library accessible through the internet. Objects can consist of digitized content like print or photographs, as well as originally produced digital content like word processor files or social media posts. In addition to storing content, digital libraries provide means for organizing, searching, and retrieving the content contained in the collection. Digital libraries can vary immensely in size and scope, and can be maintained by individuals or organizations. The digital content may be stored locally, or accessed remotely via computer networks. These information retrieval systems are able to exchange information with each other through interoperability and sustainability.
The Handel Reference Database (HRD) is the largest documentary collection on George Frideric Handel (1685–1759) and his times. It was launched in January 2008 on the server of the Center for Computer Assisted Research in the Humanities (CCARH) at Stanford University. Originally assembled by Ilias Chrissochoidis to support his PhD dissertation "Early Reception of Handel's Oratorios, 1732–1784: Narrative-Studies-Documents", it now includes about 4,000 items and 800,000 words. HRD is organized chronologically, covering the period from 1685 to 1784 and focusing on Handel's British career and reception. It includes transcriptions of printed and manuscript sources, some of which remain unpublished and external links to early secondary literature on the composer. The project received financial support from Houghton Library, Harvard University (2010–11) and UCLA's William Andrews Clark Memorial Library (2011–12).
A pathfinder is a bibliography created to help begin research in a particular topic or subject area.. Pathfinders produced by the Library of Congress are known as "tracer bullets". What is special about a pathfinder is that it only refers to the information in a specific location, i.e. the shelves of a local library.
Library Genesis (LibGen) is a file-sharing based shadow library website for scholarly journal articles, academic and general-interest books, images, comics, audiobooks, and magazines. The site enables free access to content that is otherwise paywalled or not digitized elsewhere. LibGen describes itself as a "links aggregator", providing a searchable database of items "collected from publicly available public Internet resources" as well as files uploaded "from users".
