OAIster describes itself as "a union catalog of millions of records representing open access resources that was built by harvesting from open access collections worldwide using the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH)". It is effectively a meta-search service for ePrint or institutional archives, which "harvests" descriptive metadata (records) from a number of archives and includes links to the archived documents.

Since 2009, OAIster has been managed by OCLC (Online Computer Library Center – a non-profit computer library service and research organization), and now includes more than 25 million records representing digital resources from more than 1,100 contributors.

Most of the records from OAIster lead to online materials. Many of these cannot be found through Google as they are part of the "Deep Web".

The range of open access digital materials that are available via OAIster includes:

• Digitized (scanned) books, journal articles, newspapers, and manuscripts
• Digital text
• Theses and research papers
• Audio files (wav, mp3)
• Video files (mp4, QuickTime)
• Photographic images (jpeg, tiff, gif)
• Data sets (downloadable statistical information)

Please note that some of the archives that OAIster searches are discipline-based and some are institution-based. One significant discipline-based archive that is available in OAIster is arXiv, an open access archive of electronic preprints of scientific papers in the subject fields of physics, mathematics, non-linear sciences, computer science, quantitative biology, quantitative finance, and statistics. ArXiv is owned and operated by Cornell University and can be accessed and searched as a resource in its own right.

Meanwhile, OAIster is also available within WorldCat, OCLC’s free network of library content and services, where search results will include OAIster records along with records from thousands of libraries worldwide.

OTseeker is a free, Australian web-based database that contains citations and abstracts of systematic reviews, randomised controlled trials, and other resources relevant to Occupational Therapy. Most of the trials have been critically appraised and rated to assist in the evaluation of their validity and interpretability.

The trials in OTSeeker have been sourced by:

• systematic searches of MEDLINE, CINAHL, ERIC, EMBASE Rehabilitation and Physical Medicine, AMED, PsycINFO, the Cochrane Library, CancerLit, and Ageline.
• auto-alert strategies in MEDLINE, CINAHL, EMBASE, AMED and PsycINFO
• hand-searching of selected journals.

Some of the records have links to the full-text of the item. If there is no link to the full-text, you can search for it using the Library's main search tool, Primo Search.

OTSeeker is similar to three other databases, all developed in Australia: PEDro (covering physiotherapy), speechBITE (speech therapy) and psycBITE (acquired brain injury).

OVID provides access to a number of indexing databases and other resources, in a wide range of subjects, including Business, Science, Health, Social sciences, Computing, Education, Sport, and Psychology.

Most of these resources can be searched in combination, as well as individually.

Some of the resources include links to full text content via the Journals@Ovid collection.

There is also access here to a collection of journals which CSU subscribes to in full-text – CSU Full Text Journals@Ovid (this is a subset of the Journals@Ovid collection) – and to a collection of eBooks – Books@Ovid.
