Not to mention that a single book can be loaned multiple times over the year.  So, if you have a pay per loan rate of £0.0629, it would only have be loaned 8 times over the year to match the rate of one sale (for the author).  Not to mention that they probably get the royalty from the first sale as well (or maybe not as part of the pay per loan agreement - I have no idea).<p>So, the pay per loan rate is probably pretty good.
