Data and index pages

As found in a book saying about Index pages:
'Unlike data pages, there is no limit to the total number of entries that
can be made on an index page.'
What is that mean ?
It's wrong. An index page has the exact same limit as a data page. There's
8k in a page minus the header size and the slot array and that's all the
space that available on the page for records (entries). There's a finite
limit defined using the minimum possible record size plus the slot array
overhead for each record - I'd work it out for you exactly but I can't
remember the minimum possible record size off the top of my head. The max is
somewhere around 310-320 records per page though.
