I put up a table of worst leads on here - it was taken from Blackwood - The complete book of opening leads. I  don't have the book anymore so can't reproduce it.

The original methods which many American experts use is called Journalist leads - this includes 3/5 and Rusinow. The book most Americans refer to is Journalist Leads by Lawrence Rosler and Jeff Rubens which outlines the whole method with zillions of examples (but you'll have to get it second hand). There were earlier books recommending the same methods in Europe. A very brief summary of journalist leads can be found at http://www.cavendish.demon.co.uk/bridge/journlst.htm .

 

If you want an exploration of 3/5 leads I can write a few thoughts...I used to play them all the time and they are great for people who count everything on defense...(Im too lazy/incompetent most of the time)...but I gave them up for different methods.
