Questions about the Northbrook list
Where does this data come from?
The Illinois attorney registry, which the state publishes as a public record. We do not buy or merge third-party compiled lists.
Does every row have an email address?
No — and no honest attorney list has one for every row. The roster on this page carries no email column at all. We hold addresses for 340 attorneys in Northbrook (41%), sold as the Northbrook email file above.
Where do the email addresses come from?
The Illinois bar publishes a member email address on its own record, so most of ours come straight from the registry rather than from a crawl. Either way an address is only sold once it belongs to a named, currently-licensed attorney.
How current is it?
Last refreshed 2026-09-06 — that is the date of the scan behind these figures, not a promise of a schedule.
