I'm a librarian who loves anime, manga, and reading a wide variety of genres.
This was published in 1972 and therefore doesn't fit in with my usual work-related reading, but it's been mentioned several times lately in a cataloging Facebook group I'm part of. I'm looking forward to the drama of such chapters as "An Elusive Library of Congress Card" ("The bibliographic search unit in a university library has failed to discover a Library of Congress card for a book on which a cataloger has spent a considerable time.") and "An Author Finds His Book Misclassified" ("A visiting scholar from France checks the university library catalog and discovers that his own book has been given a wrong classification number and subject entry.").
