摘要： In the higher priced grade of books, which for example are known generally as the "hard copies" as distinguished from the more economically priced so-called "paper backs", it is customary to protect the books by a so-called dust shield or protective book cover. These protective covers are generally highly colored and carry a pictorial image of the author, or of some primary incident in the story. When it is necessary to put down the book without finishing reading it in one sitting, it is desirable to have a book marker so that one's place can be quickly and easily found so that the story can be continued without regression. Frequently a portion of a page of newspaper or magazine is torn off to provide a small book marker. By the present invention a narrow perforated edge of the fold under flap of the book cover may be torn off from the dust shield or cover and used as a book marker to mark one's place in the book. As frequently happens, two parties in a family may be alternately reading the same book simultaneously. To accommodate this contingency the marginal edges on both sides of the dust shields can have narrow perforated sections which can be torn off to provide two book markers. Opposite sides of the dust shield can conveniently be colored differently so that it is possible to readily distinguish one's book marker from the other. Similarly, the outer edges of so-called paper backs can be turned in and perforated to render readily accessible book markers available.
摘要翻译：在价格较高的书籍中，例如通常被称为“经济复制品”，与经济价格更为优质的所谓“纸背”不同，所以习惯上用所谓的防尘罩来保护书籍，保护书封面。这些保护套通常是高度着色的，并带有作者的图画或故事中的一些主要事件。当需要放下书而没有完成在一次坐下阅读时，最好有一个书签，使人的地方可以快速，容易地找到，以便故事可以继续而无回归。通常报纸或杂志的一部分页面被撕下来提供一个小书签。通过本发明，书盖的折叠下方的折叠的狭窄的穿孔边缘可以从防尘罩或盖子上撕下，并用作书签，以标记书本中的位置。经常发生的事情，家庭中的两方可能会同时阅读同一本书。为了适应这种紧急情况，防尘罩两侧的边缘可以具有窄的穿孔部分，可以被撕开以提供两个书签。防尘罩的两侧可以方便地进行不同的着色，从而可以容易地将书签与另一个区分开来。类似地，所谓的纸背的外边缘可以被转入和穿孔，以使易于访问的书签可用。
