OK so ISBN #'s are really expensive. Not a justifiable expense for the likely sales income from a chap. OK I can deal with that. So I look up ISSN #'s and think I've hit the jackpot, they're FREE! They're also for series, like a magazine with a monthly issue under the same title. I'm thinking I'm not even interested in talking Shaela into publishing a chapbook for me on a monthly basis.
Write what you know. Historically proven to be pretty good advice. I'm trying to keep it in mind here, but I don't know very much. Maybe my chapbook manuscript #2 will be poetry about labor and delivery. I know that pretty damn well. Not a very marketable genre of poetry though. Hmmm.
I fear I will have to delve into my neuroses to do this well. That's a wealth of subject matter eh?
