I recently came across the website Logo Of The Day. Designers submit their logos, which are then screened by a professional, practicing logo designer. They are judged on the design & concept, creativity, scalability, appropriateness, usability and memorability of the logo before being awarded the LOTD award. Each day, the selected winner’s logo is posted on the site.
Logo Of The Day was started by Graphic Designer Jacob Cass, in 2008. Recently Mr. Cass compiled some of the winning logos into a book called Logo Design: Inspiration E-Book. The 70 page book features over 1,000 logos and it’s free to download. Check it out here: http://justcreative.com/2014/09/23/free-logo-design-inspiration-ebook/
