What is the difference between wishlist & requested?

Are you referring to the Tabs on your My Account Page? You will have a Books I've Requested tab where books that the request has already went through for and they are just waiting for the person to accept the request or to mark them mailed. You will also have a Wish List Hold tab, on that tab you need to accept the Wish List offer within 48 hours in order to request the book being offered to you; then the book will move to your Books I've Requested tab.

Requests happen when a book is available, the Wish List comes into play when the book wasn't or isn't available and you wait in line until one is offered to you.

Any book that you have been requested to mail out is "requested". It will show on your tab like Melanie describes.

Books that you post into PBS:

1. are offered directly to someone waiting in a Wish List line for it (in the case where there are people waiting for copies to become available), or
2. are placed on your bookshelf (in the case where there are already other copies of the book available, or, perhaps no copies available, but also nobody waiting in a Wish List line).

In both of these cases, the books will be requested from you, although Wish Listed books will be requested quite quickly, as the first person in line is offered the book when you post it. Books placed on your bookshelf may be requested quickly or slowly, depending on how many copies there already are, and how much demand there is for that book. Books posted to bookshelves are in what is called the "FIFO" line, (First In, First Out) meaning that people who order books are ordering from the person who posted the earliest copy of that book. (So, in other words, when you post a book that already has 10 copies available on PBS, your copy of the book will be the 11th to be requested, as people order that book from PBS).

When you're looking a certain book-REQUEST means it's available on someone's bookshelf, go ahead nd order it. WISH LIST means that there are no copies in the system. No one has posted it at this time but if you want to get in line we'll send you one if it becomes available.
