If you write and publish eBooks, sooner or later you will probably be faced with a dilemma - should you create your eBooks as .exe files or .pdf files?

PDF, which stands for Portable Document Format, is file extension for files created with Adobe Acrobat.

Exe, which stands for 'executable', is extension for files created by eBook compilers.

PDF is widely considered to be 'industry standard' for eBook publishing, and for good reason. Here are some of advantages of PDF files over exe files:

(1) With most eBook compilers you have to set up each page of your eBook as a separate web page. With Adobe Acrobat you can use a single MS Word file as source document.

(2) PDF files automatically number each page - exe files don't.

(3) PDF files are very easy to edit - you can insert pages, replace pages and delete pages (and page numbering is automatically adjusted).

(4) Printing from a PDF file is much easier than printing from an .exe file.

(5) The 'bookmark' column on left side of a PDF file makes naviagtion very easy - much easier than in an exe file.

There are millions of ebooks online and everyday there are more then one hundred new ebooks that hit stands of online library. Some of them are free, other not. But they are all full of fresh information or they will be forgotten.

As a reader, it's tough to decide which one to read and which not. That's why most surfers do pretty much same thing they do in a real library.

Remember last time you were in a real library or bookstore? If you are like me, you will more than likely base your decision of reading or buying a book on first stimulus that catch your eye.

And that one stimulus is COVER.

And that's way everyone decides to read or buy a book: THEY LOOK AT THE COVER AND MAKE THEIR DECISION BASED ON IT!

So, how do you recognize a great cover?

First, it has to be an eye-catching cover so visitor will pick up your ebook instead of ebook of your competitors.

Second, even if cover piqued your visitor's attention it also have to be interesting enough to make him actually read your ebook.

How can you make your cover stand out in a sea of covers?
