Good to have your company, Sandy. Several publishers and many independent authors strongly oppose DRM padlocks.
You don't list a reading device, but even if you are still ebook-reading on a PC or laptop, it's an idea to download the excellent and free Calibre Library software (
http://www.calibre-ebook.com)
What you'll find is not only the best library management software available (thousands here at MobileRead and more than a million others swear by it), but among its features is a section called 'Get Books'. There you will find clearly marked those publishers and titles that don't carry any form of DRM.
Luck, happy e-reading and best wishes. Neil
