Here are some tools to help find an address. Best way: simply ask the person. Sometimes that is not possible. If one of the following doesn't work, try another.

Here are some approaches depending on what information you already have:

- Search special lists such as the
*membership directory*of the AMS - Search a "company" directory, such as Cornell University (www.cornell.edu) links to send a message to the author.
- Newspaper and magazine articles on the Internet frequently have links to send a message to the author.
- Do a Google search:
*Scholarly articles frequently have the authors' addresses*: - Google has several tools for Special Searches

**Finding Addresses of
Mathematicians**

- Combined Membership List of the AMS, MAA, SIAM search form (You can use * as a "wild card", except in the first character. Not case sensitive.)
- European Mathematical Society
- Societe Mathematique de France
- Many Mathematics Departments now have Web servers listing addresses. Thus, look in the Web page of the appropriate department: Mathematics Department Web Pages
- Try looking in a mathematics Preprint Server. One of the largest is Mathematics ArXive
- Use Google search.
- If you know both the family name and the name of the computer
they use, then on a Unix computer try
*finger*to find the email address.

For a mathematician at a university in Canada or the USA,*if*you know the Internet name of the university, as`toronto.edu`, then a good first guess for their computer is`math.toronto.edu`and try**finger**`FamilyName@math.toronto.edu`.

Following the approaches listed above:

- If you know the person is a member of a
*professional society*or is on some electronic address list, then try that. The above searches in the AMS Membership List, the French Mathematical Society (SMF), and the Geometer's Address List are examples. - If you know the name of the person's
*home organization*, such as Cornell University, you can search for Cornell's directory in various lists of telephone books:- Some People Pointing Resources, assembled by the American. Math. Soc.

- Lookup by name or email address, especially useful for those who have posted Usenet messages.

The search procedures are improving quickly.
