Getting references after a company closes - 11 months and counting

I worry a reference will only confirm dates of employment. This is my first time dealing with any of this. HR only confirms titles and dates. Is a client acceptable?

I kept a note of my results so my references could be specific. They appreciated it.

Thanks for writing this out. I went through something close to it last year, and it got easier once I kept a simple log of every call and form.
