There are several ways to search this database of author citations of papers entered into the Fritsch Collection

•  In the ‘ Authors ' box type in an author's last name and click ‘Find Citations'. Results will include this name as first or subsequent author.

•  In the ‘ Title ' box enter any word or phrase you wish to search on which may occur in a title and click ‘Find Citations'. The more complete the word the fewer results – eg. ‘diatom' gives more results than ‘diatoms'.

•  In ‘ Keywords ' click this heading to see a list of keywords used (note that under ‘Description' are suggestions of other keywords to use). Type in the keyword, or use Copy/Paste, and click ‘Find Citations'.

•  In ‘ Geographic Keywords ' click this heading to link to a similar list of geographic locations, mostly countries, used. Type in the geographic keyword, or use Copy/Paste, and click ‘Find Citations'.

You can search on more than one box at a time (eg ‘ Spain ' and ‘Chlorophyceae'). You can also search on more than one term at a time in ‘Keywords' or ‘Geographic keywords' by separating multiple terms with a semicolon (;)

To do a new search click on the ‘Search Citations' link which will clear all search terms.
