Hi Jon!
Nice to see you chippin' in.
So may I ask you (Jon & maddz) to go into more detail and give a step-by-step description of how you check your library before making purchases?
For example, do you first browse, see something that interests you, then search your library to see if you have it and then buy it OR do you start searching a book you have in mind and proceed looking to buy it if you already don't have it? Or is there some other method to it?
Thank you for all the responses so far, you've been really helpful
