Create a calculation called cYear (result is number) with: Year (yourDateField ). Also create a field called sPages (type is summary) and select Total of Pages (pages should be a number).
Go to File > Manage Database > Relationships and select your table occurrence until it highlights. Then click from below the ++ to duplicate it. Point and drag from Dates::cYear to Dates 2::cYear. Any time you want to count all your pages per year, place the version of Dates 2::sPages on your layout. If you want to only count the number of pages in a specific found set (such as restricted to author etc), place the Dates:sPages field on your layout (which will respond according only to your current found set).
Create a calculation of: Year ( YourDate )
Create a summary field that counts the calc field. You can use a subsummary report grouped by the year calc or use another calc field using GetSummary (). Dont forget to sort by the break field.
