"Browse Before You Buy" & "Take It With You"
The concepts of "Browse Before You Buy" & "Take It With You" are central to purchasing books in a bookstore, yet they are missing from the selling of books on the web. That is, until now!
"Browse Before You Buy"
This is a concept which is universally practiced in bookstores, but which is absent on the web.
When you stand before a shelf of books in a bookstore, you can look at the cover which tells you something about the contents of the book. On the web, you can read an HTML page that tells you about the book. Often you can learn more on the web, because the space limitation that exists on the jacket of a book does not exist on the web. For example, user reviews are often available on the web.
In a bookstore, unless you are in a real hurry, you will open the book and browse the contents before you buy. This you cannot do on the web. At Amazon.com, etc. you cannot "see into" the book. You can only read about the book.
Now, with PDF WebSearch and FileOpen security, this has changed. FileOpen permits a digitial book in PDF format to be opened on the web, but it cannot be opened anywhere else. A user can download the PDF book, but cannot open it on the desktop (prior to purchase). A user can search and open any of the pages of the book on the web, but cannot copy/paste or print.
This is just like in a bookstore, but with one difference: There is a practical time limit to how long you can stand in the isle of a bookstore, but there is no limit to how long you can read on the web. Despite this difference, allowing web users to browse the book in digital form will allow the users to determine relevancy to their interests, which will promote sales of paper-based books and satisfied customers.
An example of PDF WebSearch in use with FileOpen security is available at www.engineering-library.com.
The use of PDF as digital books has multiple purposes. The PDF file can be a companion to a print book, or it can be a product on it's own. It can be used to promote the sale of print books.
"Take It With You"
In a bookstore, when you find that book you are looking for, you can pay for it and take it with you. Sit in the car in the parking lot, if you like, and start reading!
When you buy a book on the web, you are forced to wait for days until it arrives in the mail.
Now with PDF digital companions, the PDF version of the book can be delivered immediately. Well, almost immediately, because it must be downloaded first. But 15 minutes of downloading time is much better than days of "snail mail". If you can't wait for days to start using the book, then "crack open" the PDF version!
With FileOpen security, a PDF book can be delivered to a single desktop, and not copied and distributed. Therefore one print book and one digital PDF version of the book can be given to a paying customer.
Web-based Book Portals are ready for the Next Level
Online bookstores like amazon.com and barnes&noble.com, having succeeding in telling us all about the books they are selling, are now technically capable of "letting us get into" the books with the PDF file format. Whether they actually do this or not is a separate question. But the evolution of selling books on the web must continue. PDF WebSearch and FileOpen can enable the next level for book portals.
