It is also important to note that there has been some disagreements with Goldgar's sense of the importance of journals in the Republic of Letters. Françoise Waquet has argued that literary journals did not in fact replace the "commerce de lettres". Journals depended on letters for their own information. Moreover, the periodical press often failed to satisfy the scholarly desire for news. Its publication and sale were often too slow to satisfy readers, and its discussions of books and news could seem incomplete for such reasons, as specialization, religious bias, or simple distortion. Letters clearly remained desirable and useful. Yet it is certain that, from the time journals became a central feature of the Republic of Letters, many readers gained their news primarily from that source.
