First of all, I suggest you look for the book of accounting practice license. Do not need to look at laws and regulations. First of all, you should understand the knowledge in the accounting foundation, remember the concepts of assets, income and rights, read the whole accounting foundation, and then you can read the regulations. Well, after you finish reading these two books, I suggest you read the book "Intermediate Accounting Practice". I recommend you to read two more books, "Teach you how to do accounts by hand" and "7-day guide for cashiers", which may help you. If the library can't find it, just look online. I prefer to go to Dangdang because I'm not too worried about buying books of poor quality. hope this helps
