I wasn't keeping track of how many authors have supported the blog by putting their books to the page 69 test, but Linda L. Richards was. On Monday she posted an item at the January Magazine blog marking the 100th entry.
Linda is not only one of the first authors to help the series get started--read her entry for Calculated Loss here--but her sites January Magazine and its sibling The Rap Sheet are responsible for leads to many of the other books that have appeared in the series.
Thanks to Linda for the note on the 100th entry in the page 69 series, and to all the participants who have put their books to the test.
See the current list at the end of the 103rd entry.
