Dear Miss Snark,
Many agent blogs say it's a good idea to query agents of books similar to your own project. My manuscript is historical humour, which isn't exactly the biggest genre out there. I drew up a list of authors working in a similar vein, but I haven't been able to track down their agents with my google-fu. Searching for "author name" "literary agent" or similar terms gets me hundreds of pages and no helpful results. Author's webpages don't tend to list the information: probably to avoid being inundated with hundreds of copycat queries. Barring author dedications, is there a way to find which agent represents a specific author?
This is advice that sounds good in theory, and sux in practicality.
You don't have time to read enough books to find out if they are "like yours" before querying agents anyway. And besides, I don't want books that are just like other people on my list. I want something fresh and new.
And some books that are "like yours" may be represented by people who don't like the books at all but inherited them from colleagues, or the author changed genre.
What you do instead is figure out your category and query agents who represent novels in that category. Don't make this any harder than it is, and don't go crazy trying to find the perfect match. Query widely. Write well. Forget all that cross referencing, colored pens, power point presentations and ....oh wait, that's not you, that's me. Never mind.
The reason the advice "query agents who represent books like yours" sux is not cause it's hard to find out who reps what cause you can find those by looking at Publishers Marketplace or in the rights lists of publishers catalogs, and usually on agent's websites.
