For free deposition advice, why not try my three podcasts on advanced deposition techniques? Originally posted Legal Underground, I'm reprising them here (yet again). Just follow the links--
Combined, these three podcasts have now had nearly 3,000 downloads. You can listen on a computer with speakers or even better, on any iPod or mp3 player. The 48 other podcasts I did before giving it up can be found here.
If you like what you hear on the deposition podcasts, don't forget my book: Deposition Checklists & Strategies (James Publishing, 2d Ed. 2007).
