The omission of people's city, state and zip in a confidential resume means that they are not searchable once entered into a database. I understand that people like to post confidentially on job boards as there is a means for confidential return communication, but once that resume gets into some other ogranization's hand, it is useless without contact info. And more often than not (maybe 75% or more of the time), their resumes are being farmed out elsewhere from the job boards, and are therefore useless without personal information.

Perhaps the most frequent mistake I see made is people who put their address and phone on their resume but don't put their email address, not realizing that their resume document may get separated from their original submission email or their job board resume entry. Resumes always always get detached from emails or job boards for review, so you shouldn't omit an email address on the actual resume.
I've never recruited from job boards, so this is useful information to have. On a similar note, I've received resumes sent directly to me without containing any contact info, just a name, which is also strange. So today's message: Contact info -- use it.
