After studying this section you will know how and where to find the recent published literature you need by using the advanced search method "citation search".

• A citation search (checking the citations of a publication) gives you more recently published literature. This is a more advanced search method
• Snowballing is using the reference list of a key document as a starting point to find more literature
• Pearl growing is searching for better and new search terms in SmartCat or databases.

• Use Boolean searching
• Use wild cards, synonyms and quotation marks.
• Use a thesaurus to find broader, narrower or related terms.
• Use the options for broadening or limiting your search when you get too few or too many results.

Many of the publications you find will contain relevant bibliographies. The disadvantage is that these titles always pre-date the publication in which they are mentioned.

Citation searches reverse this process: who has cited the publication you have found? In this way you will find recent literature.

Some databases (e.g. Web of Science) have this option.
