Microsoft® SQL Server® 2012 Reporting Services eBook question

For the title Microsoft® SQL Server® 2012 Reporting Services (eBook ISBN 978-0-7356-5819-6) it shows publication date of December 2012. However when you purchase the book and download it, it only contains 3 chapters. Is this the start date of the eBook rather than the actual finish date?

  • Hi Ken,
    That's a Microsoft PrePress title, which is much like our "Early Release eBooks". As more content becomes available we will update your copy of the eBook and notify you that new content is ready to be downloaded. The final version of the eBook is expected to be released sometime in April, when the print version is released.

    Cheers,
