Author Jonathan Brown has experienced firsthand the differences between releasing books together or separately. In 2019, he released A Boxing Trainer’s Journey and Moose’s Law separately in Los Angeles, but together at an event in Vancouver. He found that the Vancouver event was more successful than his two separate events. One reason he believes more people attended in Vancouver is because it might have been asking a bit too much of people to attend multiple events for one author. Even if they want to support you, there is only so much time they can dedicate to attending book events. Brown also advises that if you are releasing multiple books around the same time, it may be wiser to hold one event as soon as possible instead of spreading them out, because bookstores and other venues are more interested in current, new releases.
