Items may be placed in the Clipboard on most of the regular pages either by dragging/dropping them from a Listing or by tagging Listing items and adding them by pressing a button. Clipboard items may include Articles, Books, Issues, Periodicals, and Authors. The Clipboard is saved as a browser cookie.
Then, on the Library page, Clipboard items may be moved into the Library, once again either by dragging/dropping or by tagging. The primary purpose of the Clipboard is to serve as a temporary-storage conduit for the Library.
