Jennifer Carr & Cara Griffith (both Editors, Tax Analysts) have published Parting Company With 2005:  The Year in Review, 39 State Tax Notes 65 (Jan. 9, 2006), also available on the Tax Analysts web site as Doc 2006-113, 2006 STT 5-2. Here is the Introduction:

"Parting is such sweet sorrow." Sure, Shakespeare wrote it, but does it really make sense? We’re not so sure. Regardless of whether it’s sweet sorrow or not, parting was definitely the pop culture theme of 2005: Jen and Brad (we thought they were forever), Nick and Jessica, and even Paris Hilton and her The Simple Life sidekick, Nicole Richie, parted company. In more serious news, the war in Iraq continued to dominate headlines, with an increasing number of Americans skeptical of our continued military presence. In the midst of war, we also saw one of America’s great cities devastated by natural disaster, got a new pope, and learned that W. Mark Felt was Deep Throat. Having recently parted company with 2005, we thought it was only fitting to have a look back at some of the sweetest (or for some, the most sorrowful) state and local tax developments of the past year.
