QR codes

My OS is win 7 prof 64 bit and I use office 2007.  I am trying to enter data of books into the database.  once entered, I would like to have some sort of a barcode  and to retrieve this book onto the screen,  I could scan the barcode. this will might be a better way of typing the title or isbn to search.  Also many of these books do not have the isbn bar code on the book or anywhere on it.
Can the experts advise what is the best strategy to use for this.  
Probably somke sort of bar code that even cell phones are capable of using.  Is QR codes the answer, if yes, can u please point me where I can look up the documentation for someone who has no knowledge about this.  Thank u

Are you trying to use the bar code(s) for entering data or for retrieving data?
If a user has a bar code, wouldn't they already have the book?   This is the part of your problem description that makes the least sense to me.

I intend to enter the data of the book into an Access db and then when I have to update the data, instead of searching by title or isbn number, which involve typing, I am thinking of scanning the bar code which will bring up the record for my editing.  Sldo domr og yhr books have very close titles, thus making sure the correct is displayed for editing a bit more cumbersome.    Is this a good idea or just not worth the effort. thank u.
How are you going to print and look up the bar code?  You could have an entire book of bar codes, just to be able to locate the book.

I don't see a problem with keyboard lookups.  This has been a reliable method for many years.

If you want to add phonetic search capabilities to your application, then that might help with spelling errors.  I am not familiar with "Sldo domr og yhr books", so I can't put the difficulty of book differentiation in any context.
