In fact, though all English and American statutes have been avowedly for "the encouragement of learning" and "the progress of science and useful arts," the courts have construed the laws to cover in the widest sense any "useful book." The courts have indeed denied copyright protection only to works having absolutely no literary quality, such as advertisements (unless they contain original literary matter) and advertising cuts, labels, blank books, or blank forms. Even booksellers' and other trade catalogues, having descriptive notes or distinctive arrangement and combination, can be copyrighted. Compilations of existing materials, from common sources, arranged and combined in an original and useful form, receive the same protection as wholly original matter. Drone schedules English or American judicial constructions extending this principle to: (1) general miscellaneous compilations; (2) annotations consisting of common materials; (3) dictionaries; (4) books of chronology; (5) gazetteers; (6) itineraries, road and guide books; (7) directories; (8) maps and charts; (9) calendars; (10) catalogues; (11) mathematical tables; (12) a list of hounds; (13) abstracts of titles to lands; and collections of (14) statistics, (15) statutory forms, (16) recipes, and (17) designs--several of which classes are now specifically included in the new American statute. Later decisions have confirmed several of these categories and have specified also (18) trotting records; (19) racing charts; (20) newspaper reports of public speeches; (21) telegraphic codes; (22) mining reports; (23) a tradesman's alphabetical list of wares; (24) a list of public documents; (25) mathematical calculations; (26) legal forms; (27) an application form for membership; (28) complications of railroad time-tables; (29) commercial circulars, protected by a Canadian decision; (30) school registers, and (31) stud book list of horses. {Sidenote: Exclusions adjudicated} On the other hand, the courts have declined to include as proper subjects of copyright (a) methods or plans, as for compiling credit-ratings or systems, as in the case of (b) shorthand, (c) trading stamps or coupons as described in a copyrighted advertising pamphlet, or (d) of letter-file indexes; (e) a sleeve pattern chart; (f) the face of a barometer; (g) a railway ticket designed for punching; (h) a day's sporting tips; (i) blank books; or (j) blank forms, as a cricket score-card; and (k) monograms. {Sidenote: Inclusions defined} In the new Rules and Regulations of the Copyright Office promulgated as approved by the Librarian of Congress in 1910 as Bulletin No. 15, it is said as to books:
