completed collections, for it would produce a most unsightly effect, even if it were practicable, to insert mention of new parts of a series as they arrived in the library.
(6) The printer's or publisher's names are added to all books where known. In the Museum catalogue the names of publishers are generally omitted from the titles of foreign books published after 1699, but the insertion of this information has been shown to be of so much use in differentiating editions, that in the headings of Greek and Latin writers lately printed for the General Catalogue {e.g. Terence) the names have been added to all editions.
(7) The "notes" at the foot of the entries contain descriptions of bindings, which are rarely found in the Museum catalogue. (This omission, we believe, will in future be avoided in the latter compilation.)
(8) The treatment of undated books in the Bibliotheque Nationale catalogue is unheroic, no attempt being made to supply dates, except, apparently, in the case of modern French books, which naturally get themselves dated, with more or less accuracy, through the depot legal. The order of the entries, however, being chronological under each work, dates are evidently conjectured by the compilers of the catalogue, though not expressed. It seems most regrettable that no assistance is afforded to the student on this point.
(9) Another omission, which used to characterise the British Museum catalogue until about ten years ago, is the omission of the pagination.
