These are a few valuable links to SPSS sites that I have come across, which you may find helpful.
Get SPSS from OSU. OSU students can get a copy of SPSS from the University. You'll need to go to Baker Systems to get the codes and register, but it can be downloaded from softwaretogo.osu.edu.
David Garson's Statsnotes. Dr. Garson teaches at North Carolina State University and writes some of the clearest, easiest to understand papers on a variety of statistical subjects.
The SPSS News Group. Subscribe to the group using the link on the page (the link I give is for Google Groups but you can use any news reader you wish. This is a great site to get any SPSS question answered -- from simple to complex. If you subscribe to the group, you can also get updates e-mailed to you whenever a new posting occurs. Many will be of no interest, so look over the e-mail for the ones you need.
Raynald Levesque's SPSS site. Wow! The guy has created tons of syntax, scripts, and macros. This is very helpful if you have a special task that needs to be accomplished and you don't have a clue how to write the syntax. (You are writing syntax aren't you? Shame on you if you're not.) This site will save you hours of work.
UCLA's SPSS help site. Why doesn't OSU do this?
Norusis, M. J. (2004 and beyond). SPSS XX.x guide to data analysis. Upper Saddle River, NJ: Prentice Hall.
This book is reprinted with every new version of SPSS. To the best I can tell, it's always the same and will be unless some radical change is made to SPSS. Get the most current version and don't bother updating unless it stops working for you (I'm using the book for version 12.0 and it works just fine on version 14.0). There are other books in the series "companion" series (Statistical Procedures and Advanced Statistical Procedures) that may address your needs too.
