My husband is a published writer, and has done a number of things, from writers' workshops (with authors like Kurt Vonnegut and Jill McCorkle) to Writers' Digest, to working with literary agents. It's a long and frustrating process, so do your homework up front.
You don't start with a title - you start with an idea, you write a proposal, and you shop it to literary agents. That means really identifying what "educational" focus or direction you envision. You also must must MUST research what else has been done in this area. There is nothing more frustrating than working hard on something and finding out "It's been done dozens of times before" from agents and publishers. Also, the book industry is very much depressed at this time - publishers are looking for guaranteed best sellers. You could look into small independent publishers - the Independent Publishers have an association that includes university presses and others. But start with a few large bookstores and look through the section where your book will be - self-help or inspiration, whatever it is. Then really look at what's already there, and what "hole" remains.
You ask about the best way to attribute to the contributers? What do you mean? Do you mean how to find them and request permission to use their work? Or do you mean how to thank/highlight them once you get permission? You do realize, don't you, that writers retain the copyrights to their work and you cannot use it at all, in part or in whole, without their permission and (probably) compensating them? This is their creative work product, they own it, and you are in violation of the law if you use anything of theirs. You can't make money of their work and expect them to make nothing. They will not allow you to use anything unless and until you have a precise outline, a direction, a theme, etc.
Once you get all that done, and start choosing and compiling an anthology, an overall philosophy or purpose will emerge. The title will come from that. One of the first mistakes many writers make is they choose a title and then try to fit the content into that. It's actually backwards - you start with an idea, a concept. Always. You may also find that a prospective publisher will suggest a new title - so you don't want to be locked into the title but to the book itself. Also, you absolutely have to research potential titles to see if they've been used before. Same copyright problem as mentioned above, plus complete confusion among the buying public.
Hope this helps.
