Abstract: A portable book stand is adapted for attachment to the back of a pew, bench, chair or similar item, as well as free-standing use on a flat surface such as a table. The book stand may include two separate folding arms attached to the rear surface of a platform on which a book rests. The angle of the platform relative to the reader can be varied by placing the end of one of the folding arms into a selected one of a plurality of grooves in the other folding arm. An attachment arm is used in conjunction with the two folding arms to attach the book stand to the back of a pew, chair, bench or similar support. One folding arm is mounted on a folding assist segment, allowing one folding arm to fold on top of the other without interference.
