I'd like to access whois history starting with year 2007 or earlier for free. Domaintools is kind of expensive for my purposes. who.is seems to provide history starting with year 2009 unfortunately.

As it currently stands, this question is not a good fit for our Q&A format. We expect answers to be supported by facts, references, or specific expertise, but this question will likely solicit debate, arguments, polling, or extended discussion. If you feel that this question can be improved and possibly reopened, see the FAQ for guidance.
I don't think that you're going to find that. If you don't want to pay DomainTools, you could try their free account. I have a free account at DomainTools but it only provides limited access to what you are looking for.
An alternative is to try to back the information out from the Wayback Machine, but that isn't the easiest way to go. See the responses to this question Can I access domain registration (whois) history? (which is already linked here).
Better yet, view this inquiry for a Free/cheap Whois Api That may be more helpful. I don't know if you want to use an API, and if so what volume of queries you'll be hitting it with though.
