Each of the Government offices, many as they were, possessed its own collection of papers. These are either still in loose sheets, just as they left the office, or bound in volumes. They are indicated by the name of the Government department, the subject dealt with, and the date. The pages are of three kinds; first, there are the files or _filze_, the original minutes of the Board, written down in actual Council by the secretaries, and with the _filze_ are the dispatches or other documents upon which the Council took measures. In many of the more important departments, such as the Senate, the Ten, or the College, these _filze_ were epitomized; the substance of each day's business was written out in large volumes known as _Registri_; each entry was signed by the secretary who had made the digest, and was accepted as authentic for all purposes of reference. These registers are, in many cases, of the greatest value where the files have been destroyed or lost. They were more constantly in use, and therefore more carefully preserved; and now they frequently form our sole authority for certain periods. As a rule the registers are very full and good; they contain all that is of importance in the files; but in making research upon any point it is never safe to ignore the files where they exist. In some cases the secretaries made a further digest of the registers in volumes known as Rubrics, which contain in brief the headings of all materials to be found in the registers. As the registers sometimes supply the place of lost files, so the rubrics are occasionally our only authority where registers and files are both missing. The rubrics are often of the highest value. As an instance, we may cite the twenty volumes of rubrics to the dispatches from England between the years 1603 and 1748. The method of research, therefore, where all three kinds of documents exists is this, to examine first the rubrics, then the registers, and then the files. But the infinite subdivisions of the Government offices in Venice render the task of research somewhat bewildering; and a student cannot be certain that he has exhausted all the information on his subject, until he has examined a large number of these minor offices. He will probably find some notice of the point he is examining in the papers of the Senate or of the Ten, and, if it be a matter of home affairs, he can trace it thence through the various magistracies under whose cognizance it would come; or if it be a matter of foreign policy, he will find further information in the papers of the College.
