Addison-Wesley Professional/Prentice Hall PTR/Pearson, and O'Reilly have been kind enough to provide us with review copies of some of their books, which we will continue to raffle off as giveaways at our meetings. The publishers always ask that the persons receiving the books provide a review and/or feedback about their books.

Unigroup would like to thank both publishing companies for the support provided by their User Group programs.

As always, all of the books will be available for review at the start of the meeting.

Note: Our book supply is currently running low, and we need to restock.

       ! Students: We are looking for proof that you are
         currently enrolled in classes (rather than working
         full-time), and as such, your Student ID should show
         a CURRENT date.  We have been presented Student IDs
         containing NO dates whatsoever, and in the
         current environment, perpetual/non-expiring access
         to university facilities just does not feel right.
         If your ID contains no date, please bring
         additional proof of current enrollment.  Thanks.
