When you are looking for biographical information consider:
How much detail do you want? Just dates of birth and death? Full biographical information with references? Do you need as much bibliography, including archival references as possible?
Where was the person born? What nationality was the individual? What was their field/profession? When did the person live? Did they publish?
These two questions will help define the sources that will be useful. To know where they were born will help you find the regional search engine and identify the languages that might be useful for your search. It will also guide you to the appropriate biographical materials. If the individual was extremely famous, a general encyclopedia may answer your question. However, the encyclopedias of the area will include more information and many will also have bibliographies with each entry.
The lists in these files are taken from Saar's biograhpical archival materials. (See center box) They will give you an idea of the type of sources and material you can expect to find in the microfiche.
If you only need dates, you may find a search engine such as Google useful. Wikipedia can be helpful but you do have to be wary of the information as it is not reviewed.
You can also identify regional search engines with tools such as Search Engine Colossus. Library catalogs are also a quick source for this information if the person published. If the individual is obscure you may need to turn to much more obscure sources. The first rule, don't "reinvent the wheel".
If you need a significant amount of information, perhaps a bibliography of works by and/or about the individual you will need a biographical resource such as a subject encyclopedia. There are any number of such sources and identifying the one you need can take time. It often helps to start with a more general biographical index.
The "World Biographical Information System" is such a source. This online index provides references to articles in a source we own on microfiche. Using the source is a multi-step project. You begin by searching the online index to see if the person of interest is included. If you choose to do a biographical search you can tailor your search by a number of indexes:
