Since the American occupation of the island, four public libraries have been established. Two of them are exclusively Spanish, the Circulating Scholastic Library, inaugurated in San Juan on February 22, 1901, by Don Pedro Carlos Timothe, and the Circulating Scholastic Library of Yauco, established a month later under the auspices of S. Egózene of that town. The two others are, one, largely English, the Pedagogical Library, established under the auspices of the Commissioner of Education, and the San Juan Free Library, to which Mr. Andrew Carnegie has given $100,000, and which is polyglot, and was formally opened to the public April 20, 1901. There is also a growing number of libraries in the public schools. From the above data it appears that, owing to the peculiar conditions that obtained in this island, the people of Puerto Rico were very slow in joining the movement of intellectual expansion which began in Spanish America in the eighteenth century. They did so at last, unaided and with their own limited resources, even before the obstacles placed in their way by the Government were removed. If they have not achieved more, it is because within the last few decades the island has been unfortunate in more than one respect. Now that a new era has dawned, it may reasonably be expected that the increased opportunities for intellectual development afforded them will be duly appreciated and taken advantage of by the people, and if we may judge from the eagerness with which the youth of the capital reads the books of the San Juan Free Library, it seems clear that the seed so recently sown has fallen in fruitful soil. * * * * * The history of the Press in Puerto Rico is short. The first printing machine was introduced by the Government in 1807 for the purpose of publishing the Official Gazette. No serious attempt at publication of any periodical for the people was made till the commencement of the second constitutional period (1820-'23), when, for the first time in the island's history, public affairs could be discussed without the risk of imprisonment or banishment. The right of association was also recognized. The Society of Liberal Lovers of the Country and the Society of Lovers of Science were formed about this time. The Investigator and the Constitutional Gazette were published and gave food for nightly discussions on political and social questions in the coffee-house on the Marina.
