Two websites I came across today (plus several interesting links on these pages);
https://www.univie.ac.at/adg/schwarz/multiple.html and http://exoplanetes.esep.pro/index.php/en/
Searching for (additional) exoplanets in multiple star systems might be a worthwhile project as you get two or more for the price of one so to speak.
Some of you who have been involved in such work might like to comment.
