"A collection of 230 poems or more? I know of no such thing, WAV. There are dozens, hundreds, thousands of books of around thirty or so poems published by big name publishers. And there are piles of small poetry magazines to be found in bookstores and well-stocked magazine stands, most of which are quarterlies, but many monthly publications." (Don)...agreed - and, thus, if I do wish to keep the 230 together, and turn pro., probably the best thing to do would be to take my master copy, and my home-made version, to a printer, rather than a publisher. I've made 10s of copies (gifted out, as above) using an inexpensive portable photocopier - the problem is, though, the replacement cartridges for it are very expensive.
Some, as you say, like to add other media to their poems; whilst others think the challenge is to say things WITHIN the framework of just poems - I'm with the latter, but some of my myspace (Top) friends have experimented with the former.
