I'm stuck on a query, I'm hoping someone can point me to the obvious

I need to limit the results of a query based on 2 criteria:
    1- total rows grouped by column_a
    2- total rows all

given:
    books:   id , author , subject , title

i need to

    SELECT * FROM books WHERE subject= 'database'
    Limit to : no more than 10 records per 'author'
    Limit to : 100 records total

I'm really rusty on my sql this week.

Any pointers would be appreciated.
