Sounds reasonable.
So questions (again thank you much for your guidance, I'm definitely
starting the process tonight):
when I make the form to enter new data (ie. a new read book) can it be
designed to where it searches the current books in Books table and then if,
and only if, it doesn't find a match (based on author + book title), it
starts a new form for me to enter new data?
For a series, is there a way for me to do like "enter a series" and then it
would prompt ("how many books in this series") and when I put in 5, it
would then auto fill author + series name, so all I have to do is enter
book titles for the 5 books and all 5 would be added to the Books table?
Reading books twice - I don't do this often, but when I do, I expect the
pages to count twice. Best way to accomplish this is to have another field
called "Count" and then page count would be Page Count * Count (# of times
read)?
I'm getting excited about this as I've come up with another cool idea that
might be easy. I'm going to link books to the library, so for "next book in
series" would be a link that I could click and easily put on hold at the
library :) I think that this would be both awesome and relatively easy
(assuming the library has a standard method of searching which I suspect it
does).
Best,
Joel
