Tracking expenses for deductions for hobby writing a book that took several years to research before being published

So, I'm a hobby genealogist.  I have spent the better part of 10 years, as a hobby, creating an historical record of my family- from Danish England to and through all the primary early immigrants to North America.  I must say, for historians as well as family, it is a ground-breaking book.  But 10 years of expenses.  Ancestry.com, Newspapers.com, trips to England to research, etc.  I should publish this year, if my health remains good.  Books like it sell for over $100.  I will self publish, but may use some publisher advocate to lobby libraries and historical societies.  But the expenses run about $1000/year, not including technical equipment.  Trips, and I've made a half dozen, cost perhaps $4K each.  I have kept records.  How do I manage this from a tax point of view?   I do have another personal business- IT support- so I file for that using Home and Business.  I also have one other book self-published on Amazon.  It was a separate research project.  I don't make the $600 threshold on that.
