him is still working, and the day cannot be far distant when a worthy domicile will be provided for the treasures of the Berlin library. Lepsius did much for the internal regulation of the library. He spoke with special pleasure of the system introduced by him for the disposal of newly-procured books as well as of the cataloguing, and the following innovations: Here, as elsewhere, the titles of the books desired by different individuals were written upon cards and handed in. If it was impossible to satisfy the demand thus expressed, the card was simply returned, and such returns were far more frequent in the Berlin library than in any other. Lepsius therefore directed that thenceforth the cards containing such demands as could not be complied with should be kept, and he made it the duty of the higher officials of the library to find out whether the refusal was owing to any negligence of the subordinate employees. The cards requiring books which could not be furnished were preserved, and it was soon evident that certain books were repeatedly called for. These were naturally such as were particularly important for students, and Lepsius caused several copies of them to be immediately procured. He also invited the most experienced professors to supply him with the names of those works which were of special weight in their own departments, but too costly to be procured by individuals of narrow means. He proceeded upon the correct principle that precisely those books which students could not buy for themselves should be at their disposal in the library. According to his own reckoning, up to that time a third of the books demanded had not been delivered, while a year after he took the management only one-twelfth were not delivered. The scant courtesy, indeed the incivility, of the Berlin library under Pertz, had been really notorious, and presented a glaring contrast to the obliging spirit encountered in the other large German libraries, especially those of Göttingen, Munich and Leipsic. This bad reputation was in some measure improved under the administration of Lepsius.
