Two comments:

1) If sqlite isn't caching already, the operating system is. So you are not reading the authors from hard disk but from memory already

2) Is this an optimization that makes sense to look for? Even if you have one million records you want to store eventually, it will take half an hour combined. This half hour (presumably) is a one-time cost, not something you have to redo every day or every month.

It is a hard lesson to take (even though I preach it I don't follow this advice usually) but optimization should be done on a finished program and only after finding the hot spot (i.e. the lines of code where most time is spent during a typical program execution). And usually such a hot spot exists, so that 95% of the time is spent in only 5% of your code. It doesn't make much sense to optimize the other 95% of your code
