For journals, the student keeps the starting year first published, the number of issues to be published per year and the category of the journal (such as academic, newsletter, trade). Each publisher has name, address and phone. Each author has an ID number, name, address, phone, author's affiliated institution and the address of the institution. An author may be affiliated with more than one institution. The student would like to keep only authors who are participating in writing at least one book and institutions that have such authors.
