In addition to search tools, there are a number of additional tools available for the research. For example, thesauri, dictionaries and translation services can help you to collect appropriate search terms. The following list contains links to:
The Digital Object Identifier (DOI) is a durable and citable identifier for electronic documents, especially for online journal articles. With the help of the DOI URL Finder, the current URL of a document can be searched.
DOI URL Finder Enter DOI (e. g. 10.1038/35057062). Leads directly to the document or to the provider of the document.
Alternative: you can enter the DOI directly into the address bar of your browser, prefixed with "http://dx.doi.org/" (e.g.: dx.doi.org/10.1038/35057062).
Specialist journals are the most commonly used tool in many disciplines to publish research results. Knowledge of the journals of a subject and their value can therefore be of great benefit for a research.
