# Searching for articles ## Discovery Systems Discovery systems try to combine the two search methods described below by searching across many databases at once AND providing full-text access. Barbaros Library provides a discovery system that can be used to search most of their collections at once. [Click here for more information.](https://libguides.berlin-international.de/link/5#bkmrk-searching-all-bau-ho)

Advantage: Searches many databases at once and provides access to full-text.

Disadvantage: Only searches the collections of one institution and cannot be integrated with all databases.

--- ## Academic Search Engines Using an academic search engine is a convenient way to search across many databases and journals at once, and while academic search engines sometimes link directly to full-texts, you will often need to find an article using [EZB](https://libguides.berlin-international.de/books/journals-journal-articles/page/ezb-browse-all-journals) or [BAU Databases](http://library.bahcesehir.edu.tr/en/kampus-disi-erisim/) once you have the citation.

Advantage: The ability to search thousands of journals at once.

Disadvantage: Doesn't always offer full-text of citations.

Strengths and Weaknesses of Google Scholar
**Google Scholar Strengths** **Google Scholar Weaknesses**
- Getting the “big picture” of the scholarly discourse around a topic. - Viewing books, articles, conference proceedings, and more in one list. - Determining authors and publications in an area of interest. - Tracking down incomplete citations. - Limiting and sorting results by type (eg. peer reviewed articles, full-text, reviews). - Searching within a specific discipline - Browsing by journal title. - Doing a comprehensive search for a literature review. - Using controlled vocabulary to search by subject. - Emailing lists of search results.

#### [BASE](https://www.base-search.net/) BASE (Bielefeld Academic Search Engine) is a multi-disciplinary search engine to scholarly internet resources, created by Bielefeld University Library in Bielefeld, Germany. As of 2022, it had indexed over [280 million documents from over 9000 sources](https://www.base-search.net/about/en/about_statistics.php).1 #### [CORE](https://core.ac.uk/) CORE (**CO**nnecting **RE**positories) is a service provided by the Knowledge Media Institute \[Wikidata\] based at The Open University, United Kingdom.1 ### **Finding full-text with citations**

After finding a citation with an academic search engine or via the bibliography of an already acquired source, it's time to find the full-text.

#### Option 1: Search [EZB](https://libguides.berlin-international.de/books/journals-journal-articles/page/ezb-browse-all-journals) to see if BI has access to the journal #### Option 2: Search the [BAU Discovery System](http://library.bahcesehir.edu.tr/en/kampus-disi-erisim/) to see if the journal is available from BAU #### Option 3: Use the [BAU EZProxy Bookmarklet](https://libguides.berlin-international.de/books/journals-journal-articles/page/bau-ezproxy-bookmarklet) to immediately see if full-text is available via BAU --- ## Databases Another option is to search for your topic directly in a database. The advantage of this is that you don't need to search for the full-text after finding an article that's relevant. On the other hand, you may need to perform that same search in several databases. BI-accessible databases are indexed in [DBIS](https://dbis.uni-regensburg.de/dbinfo/fachliste.php?bib_id=biuas&lett=l&colors=&ocolors=).

Advantage: Full-text is immediately available to view / download.

Disadvantage: Only searches the journals available in the database being searched.
