One of the most complete and up to date listings of links to sites and articles on HP history is maintained by the HP Alumni Association. It includes links on the company, the founders, products and reminiscences, and reference sites.

The HP Alumni Association is a non-profit association of former HP employees. Membership is open to anyone who has worked as a direct HP employee continuously for at least one year – and to current HP employees who are within three months of their last working day. The HPAA is an independent volunteer organization – not endorsed or supported by the Hewlett-Packard Company.
There is no charge to join. www.hpalumni.org
