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:

  1. Search special lists such as the membership directory of the AMS
  2. Search a "company" directory, such as Cornell University ( links to send a message to the author.
  3. Newspaper and magazine articles on the Internet frequently have links to send a message to the author.
  4. Do a Google search:
    Scholarly articles frequently have the authors' addresses:
  5. Google has several tools for Special Searches
It is frequently possible to combine these, say by searching for someone else working at the same location or in the same organization. With this guess of a plausible URL you can search there. This is one of the more effective ways of locating someone in Europe where there are fewer electronic organizational directories.

Finding Addresses at the University of Pennsylvania  
Finding Addresses of Others on the Internet

Following the approaches listed above:

  1. 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.
  2. 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:
  3. Lookup by name or email address, especially useful for those who have posted Usenet messages.
If none of these work, then try one of the following:

The search procedures are improving quickly.
