Last night on the reference desk my co-worker and I had trouble helping a student locate a textbook for a tax class that was listed on the syllabus as West Federal Taxation 2011 Comprehensive
We discovered that it is not West but South-Western Federal Taxation 2011 Comprehensive volume 2011. There are three copies on reserve. This title is used by a number of tax classes so it will most likely be requested a lot.
It can also be found by keywords: federal taxation 2011 comprehensive
Hope this helps.
