Book excerpt: This important reference volume introduces readers and researchers to the treasury of printed and manuscript resources available in Irish libraries, archives, and genealogical centres. Although it is aimed principally at the Irish Diaspora--amounting to some 70 million people around the globe who can trace their ancestry back to Ireland-- Irish and non-Irish researchers alike should find the book of inestimable value for their research anywhere in Ireland. It will acquaint the user with the valuable and accessible collections in Irish repositories. Essential information on operating hours, contact information--including names, addresses, telephone and fax numbers, e-mail and website addresses--access and service information, descriptions, and the location of these repositories will prove to be immensely practical. A number of features also enhance the value of the book as a work of reference. The entries are arranged alphabetically by city or town within county, and a separate list, arranged alphabetically by type of institution, is provided for added convenience. There are lists of publications, a detailed glossary and bibliography, and an extensive index. For family and local history researchers, a brief history and description of the Irish Genealogical Project is provided along with a helpful introduction to tracing one's ancestors. Of special interest are the vital reference details for each parish in Ireland for the crucially important tithe and valuation reocrds from around 1830 in the record offices in Belfast and Dublin. The guide also provides information of practical benefit to academic researchers; professionals in the area of business, education, marketing, medicine, law, and technology; and vacationers interested in learning about local resources available to them during their stay in Ireland.
