Michael has been a professional genealogist for some time, specializing in research techniques and resources. He also writes a weekly genealogy newsletter called "Casefile Clues" for paying subscribers. These are in-depth analyses of specific records and research questions. You can obtain samples for review from his website at http://www.casefileclues.com/ Right now he's running a special--$12.00 for a year of his e-newsletters (a savings of $5 off the regular price).
While I've been doing family history research for a very long time, it never ceases to amaze me what I don't know. Reading Michael's "tips" and "Casefile Clues" has definitely opened my eyes to new avenues of research.
