A fellow author has asked me how to get an agent. The answer is: I wish I knew! At the moment I don’t have an agent, though it is not from want of trying. Each time I complete a manuscript I query numerous agents whom I think may be interested. After I began writing seriously I read somewhere that keeping a spreadsheet of agents queried is useful so I did that with my first manuscript and have done it ever since. I also query directly to (a few) publishers and add these to the bottom of the spreadsheet.
When I completed my second manuscript I created a fresh spreadsheet using some of the agents who had responded somewhat positively to the first one, plus many other agents I’d never previously queried. This was a different kind of book and one gets better at sourcing agents. Same with my third novel.
I’m currently working on a Young Adult novel, and am about halfway along with it. I have a spreadsheet prepared for it and already have several agents listed there for when I’m ready to query them.
