A high security removable page book, such as a check book, receipt book, etc. that protects against inadvertent removal of more than one page at a time and prevents removal of a page from the back of the book. In one embodiment, each page has at least one extension along one edge. The extensions on alternate pages are along different edges, preferably opposite edges. Pages are removed by alternately lifting opposite edges for alternate pages. Thus, the second and succeeding pages are not liftable until pages above have been sequentially removed. Pages preferably include indicia showing which end of each page is to be lifted. A copy sheet may be provided behind each page to record a copy of information written on the page. The copy pages may be folded out of the way. A card is hinged to the assembly in a manner permitting it to be introduced under a copy sheet to prevent print-through. In another embodiment, extensions are provided along each edge, with extensions on two opposite edges near corners cater corner from each other to leave a free corner that may be lifted for page removal.
