PREFACE xi the catalogues, books described as 8vo should be understood as being " 8vo et infra." Pure Bibliography for itself alone, like pure Science, does not often pay. The worker in one field as in the other must make his work practical. As " applied " Science often brings reward to the worker, so this specimen of " applied " Bibliography has enough of promise in it to induce its publishers to print it. Let us hope they may have no cause to regret it. L. S. L., February, 1905.
