In my house, there are a lot of books. Though none of the books are under my ownership,
I decided to make a “searchable” database of the books.
But, I hate data entry, and hence I found the solution to that.

Google provides a
Google Books Application Programming Interface which can get all the details of a
book from its International Standard Book Number.

The International Standard Book Number (ISBN) is a unique numeric commercial book identifier.

The following code is a JavaScript wrapper for the Google Books API.

Next, I needed to use my mobile camera as a barcode scanner for my computer.
So, I used the ZXing Barcode Scanner Android application together with the following
web application.

Using the above stackoverflow answer, I developed a web application which will take
a barcode as input and automatically insert the book details into a MySQL table.

However, since Google Books did not have all the book details that I have some manual
data entry had to be done.

Also, I am extremely sorry that I could not open source the code that powers this
web application, as the database contains various personally identifiable informations.
