Creating a virtual library according how many books by author
Hi, it's me again. In this opportunity I have 2 questions. The first one is about the title of this post. I want to create a virtual library (or category) only with authors, by example, with at least 10 books. How can i do that?
And the second question is about part of the first one. Where I can learn about the commands, functions, variables, etc.? So, by this way, not only I can learn, but also I can develop my own solutions and, maybe, could help others.
Please, sorry my grammar (if I made mistakes, please correct me to learn)
Regards from Lima, Perú
