Currency of publication is a basic criterion in the evaluation process. In general, books selected for both Science and Social Sciences & Humanities Editions must bear a copyright from the current year or previous five (5) years. However, books outside this range, especially in Social Sciences and Arts & Humanities subjects, are often considered for coverage with the understanding that older books in these areas are often of relatively greater value. Full address information for all authors is highly desirable, and complete bibliographic information for all cited references is essential. English language full text is highly desirable, but books with full text.
