Louise B. (Louise Beerstecher) Krause

Louise B. Krause, also listed as Louise Beerstecher Krause, was an American librarian associated with early writing on business libraries. Public-domain and library catalog records consistently connect her name with works such as The Business Library: What It Is and What It Does and Better Business Libraries.

Her writing focused on how libraries could serve commerce and industry in practical ways: organizing information, building useful collections, and helping businesspeople find what they needed efficiently. That makes her a notable voice from a period when specialized library service was becoming more professional and more closely tied to everyday work.

Biographical details about her life are not widely documented in the sources I could confirm, so it is safest to remember her chiefly through her books and her contribution to the development of business librarianship.
