发明名称 Bookmark
摘要 A printers convenience item may be added to a volume such as a book, magazine, folder containing a stack of papers or the like. The convenience item provides a bookmark which projects away from a side page in the volume so that it may fold over edges of the pages to act as a bookmark. In some embodiments the base of the bookmark is wide enough to function as a thumb tab. Preferably, the book mark is made of a durable material such as a heavy duty paper or a plastic paper substitute.
