Florence Campbell (publisher biographical note)

This is Newcastle Publishing's own biographical note on Florence Campbell, author of the 1931 numerology text Your Days Are Numbered, printed as front matter in the publisher's own edition of her work. As the publisher's own promotional account, it is a useful and appropriately labelled source for the basic biographical facts about Campbell that the publisher chose to record. Its limit is stated as plainly as its strength: it is a publisher's promotional biography written to accompany and sell the book, not an independent scholarly account of Campbell's life or of numerology's own history, so a claim about numerology's origins or validity as a system of knowledge, as opposed to Campbell's own authorship and publication history, needs a source examining that subject independently of the publisher who profits from the book.
