E-Book Central is a collection of thousands of electronic books provided through Proquest. UD primarily has access to two collections:
-eLibro Premium, includes over 70,000 titles from more than 500 publishers, 95% from Latin America and Spain, on a variety of subjects.
-Science & Technology Ebook Collection, which offers more than 28,000 carefully curated ebooks spanning coverage in all science and technology topics with exceptional strength in computers and IT, engineering, life and physical sciences, and math.
Reference books are usually encyclopedias, dictionaries, handbooks, bibliographies, guides, atlases, etc. Although largely replaced by online sources, print sources offer information not always accessible electronically. They provide ready information, background treatment of complex subjects, and, with bibliographies, guides to other sources.
