I bought 2 of Randy Anderson's DVD's and learned alot from them. I also purchased "Winter Magic" by Pat Cameron and John Summerfield, QuakerBoys "Predator Huntin'" by Dick Kirby and Wayne Gendron and "Calling Coyotes Like the Pros", by AGI( American Gunsmithing Institute).

All are very good and offer enough information to put you well on your way. I've used some of the tricks demonstrated and have had success with them. Its tough though. Those 'yotes are real, real sharp here in the northeast and don't offer a whole lot of mistakes to be made. I've blown it a few times by moving to quickly or too much, etc.
Good Luck!!!
