Subscribers - Subscribers are an instant distribution network, so make your subscription card attractive. Permissions - Be sure to get permission to reprint a work that has been previously published elsewhere. One month later, you get an official form back with a copyright stamp. It feels great. Schedules - Christmas, spring, and fall are busy times for printers.
Slow periods are summer and dead of winter.

Invoicing - Martha King advises invoicing all book sales.
