Q. Once you have an agent - would you meet with them in person often or is most contact done via phone and e-mail?
A: You could meet them in person, and it would be nice, but it’s not necessary. Sometimes, it’s just not practical if you’re in Fort Worth and she’s in Manhattan. So no, it’s not automatic or completely necessary, but does often happen. Perhaps you could meet at a writers' conference - that happens plenty.
What is more common - is a meeting between publisher, agent and writer when a book contract is in place. By that, I mean when the agent sells your book to a house and the editor wants to sit down with you personally and talk over a plan for the book. All the partners meet and talk.
On this subject, know that it is a big no-no to write to an agent and say, "I will be in town in two weeks - let's meet!" Most agents are way to busy to carve out a lunch for a writer they don't know. Stick to the normal query process.
