Here are some resources about the supportive vs exploratory/expressive approaches:
The Nuts and Bolts of Supportive Psychotherapy
A supportive approach in psychodynamic–oriented psychotherapy. An empirically supported single case study
Basic Strategies of Dynamic Supportive Therapy
Analytic vs. Dynamic Psychotherapy in the Era of Managed Care
Choosing Appropriate Techniques
The Ts position about the application of this concept alone provides me most of what I need to know about how an analytic T works. Some say a more supportive way of working dilutes the therapy in a sense that it doesn't really resemble psychoanalytic therapy, and I tend to agree.
I didn't read the articles so can't say how reliable they are, but I scanned them and found that key words and concepts are there.
Glen Gabbard is my favorite resource on all things psychoanalytic; he is also very easy to follow:
Gabbard's Treatments of Psychiatric Disorders
