For smaller contracts, with smaller and more independent publishers that accept unagented submissions, I think you can hire publishing-minded lawyers to go over the details. Miss Snark explains that “you can always find an attorney versed in intellectual property to give you some advice. You need to be VERY clear that you just want a review, not a negotiation. You also want to sent some limits on time so you don’t end up with a bill that’s bigger than your mortgage. You can also get a LOT of good legal advice about clauses that should be in book contracts from Kirsch’s Guide to the Book Contract.”
