Create a digital catalog of your personal library. If you own a smartphone such as an iPhone or a Blackberry, download a bar code scanner app. There are several apps available on either the Apple App Store or Blackberry's App World, such as RedLaser Barcode Scanner and QR Code Reader or Bakodo Barcode Scanner. Open the scanner app, and scan the bar code that is usually located on the back of a book.
Scan all the books in your personal library, and email yourself the list. A good reason to consider digitizing your book catalog is that the bar code scanner will include the name of the book, the author and the ISBN number.
Copy the information contained in the email into a spreadsheet, such as Excel. Save, and you now have a digital copy of your book catalog.
Catalog your books without a smartphone app. If you don't have one, you can still create a catalog of your books. Organize the books by author's last name and start separating even further by genre. Take down some basic information about each book. Record the title, author, year purchased, edition and copyright year. Input this information on Excel. Continue taking down this information until you have gone through all your books. Save the spreadsheet and title it, "My Books."
