My favorite catenary shape reference is "Tension Structures" by John William
Leonard of Oregon State, published by McGraw-Hill. Somewhat dated classics
in the field (I'm going on memory here, so don't quote me on these) include
a book called "Cable Structures" by Max Irvine (MIT Press), and "The Theory
of Suspension Bridges" by Sir Alfred Pugsley.

I'd like to find a thorough reference on catenaries. Specifically, I need
be able to determine the shape of a flexible tension element as a function
the load that it supports.
Actually, I'm working on strengthening an existing unreinforced stone dome
roof. The profile of the neutral axis of a dome as a compression element,
regardless of its shape, has the shape, inverted, of a flexible tension
element supporting the same load.
This is more fun than metal-plate-connected roof trusses -- IMHO.
