[](https://libguides.berlin-international.de/uploads/images/gallery/2022-02/advanced-search.png) ### Search in specific fieldsIf you're interested in learning more, see the article on [advanced search techniques](https://libguides.berlin-international.de/books/the-research-process/page/advanced-search-techniques)
#### [](https://libguides.berlin-international.de/uploads/images/gallery/2022-03/opac-search-fields.png) While Keyword is the default search, there are many additional fields that can be searched specifically by selecting them from the drop-down menu. The most relevant are *Title*, *Author* and *Subject*. #### Subject Subject headings are important because you can use them to find similar information more efficiently. Once you've found a record of interest, you may want to note the assigned subject headings to find similar items. [](https://libguides.berlin-international.de/uploads/images/gallery/2022-03/subject-headings-opac.png)Subject headings are different from keywords in that they are specific terms assigned to a subject by a subject analyst or the author.
In the library catalogue and many databases, an items's subject(s) will be a link, so that you can click on the subject heading to find similar items. You also might want to note the exact words to search them as a keyword later.Example: A title search for 'human resource management' may return dozens of results, but when combined with an author search, as in the screenshot below, only items with 'human resource management' in the title AND 'Crawshaw' as an author will be returned.
