This week I had to learn some advanced Excel techniques. As usual I went to the web to look for some ideas on how to achieve what I was looking for. When looking for information on such a broad and popular subject Google isn't my favourite engine because it tends to return many results of services and courses offering excel tuition rather than the actual tips. I used the following resources to get a much more focused set of results and ideas about what I was looking for.

Del.icio.us - This got me started in the right direction. The first couple of bookmarked sites here linked to several other Excel resources literally flooding me with Excel information.

Google video - A video hosting site might not be the first place to come in mind when looking for excel stuff. After I searched for 'excel reporting' in Google Video I found a whole series of 2mins shows by Mr. Excel on how to power-use excel.

These are some of the best sites I found after searching these sources and linking sites

• My Excel Pages - Loads of Articles on Excel
• Juice Analytics - Nifty Information Representation blog with several articles on Excel with how-tos
• Perceptual Edge - Information Representation Papers and Research
• Contextures - Good examples and how-tos on advanced excel especially on Pivot Tables
