Apparatus for supporting books or like articles; comprising: first end member including an abutment surface for supportably abutting such article, base surface extending perpendicular to said abutment surface and a butt edge defined at the intersecting edges of said abutment surface and said base surface; second end member including an abutment surface normally disposed in opposed relation to said abutment surface of said first member for supportably abutting articles therebetween, said second end member being movable relative to said first end member for adjusting the spacing between said abutment surfaces; and wherein said second end member includes a base surface extending perpendicular to said abutment surface of said second end member and a butt edge defined at the intersecting edges of said abutment surface and said base surface; at least a first cord member in a normally relaxed state extending between said first end member and said second end member, said cord member intertying said first end member and said second end member to limit the distance to which said second end member is movable away from said first end member; manually operated spindle means associated with said first end member for electively and alternately winding said cord member about a bar member of said spindle means and unwinding said cord member, a dowel accepting recess defined in said base surface of said first end member, said recess piercing said base surface at an acute angle; a dowel accepting recess defined in said base surface of said second end member, said recess piercing said base surface at an acute angle; and a dowel comprising a first end removably inserted into said dowel accepting recess of said first end member and a second end removably inserted into said dowel accepting recess of said second end member, whereby said butt edges of said first and second end members are in near abutment and said abutment surfaces of said first and second end members define an obtuse angle therebetween when said dowel is in place with both said ends of said dowel inserted in the respective dowel accepting recesses thus defining a lectern type book support, and whereby winding of said cord member to a point of tension in said cord member maintains said dowel in place.
