WebShelf allows you to organize your online experience in a way that works best for you. You can create libraries, with a bookcase containing one or more shelves. Each of these bookshelves contains books, which in turn contain pages (either online or offline*). You can fully customize libraries, shelves, books and pages with the names and descriptions you like. For example, you might create a book called recipes, which contains your favorite desserts, main dishes and so forth. WebShelf is also there if you want to research topics, such as how to start a small business. You can quickly build books about how to apply for a license, obtain certifications, connect utilities and so forth. WebShelf also allows you to customize the order of items in your libraries with shelves, books and pages easy to arrange as you please. So, you can organize your collection however you'd like, at any time. And speaking of which, each user can have their own library to collect information and it can be locked with a password, if you prefer, to avoid the possibility of someone modifying your collection of pages. * Please note that offline pages may not always appear exactly as the online version due to dynamic content used by some web pages.
