The Manufacturing Clause required that all copies of foreign literary works should be printed from type set in the United States if they were to have American protection. This was an obvious concession to American printers, since they might otherwise have opposed the Act. When the International Copyright Act of 1891 was finally passed, foreign authors had to have their works in Washington, D.C. "on or before the day of publication in this or any foreign country." This too would create a problem, but by the early 1900s British authors were granted American Copyright since it was published abroad thirty days from its deposit in Washington, D.C. This would then allow American publishers time to release an authorized edition.
