Looseleaf (or Loose-leaf) Materials

 

Looseleaf or Loose-leaf Materials

Loose-leaf publications exist in several varieties. The purpose of publishing a book in loose-leaf format is to keep it as up to date as possible. The frequency of updates depends on the publisher and the nature of how fast new developments come about in a particular subject. CCH, for example, updates the Standard Federal Tax Reporter and the Federal Securities Law Reporter weekly. BNA publishes the Daily Tax Report and the Daily Labor Report (DePaul College of Law Library now subscribes to an online version of BNA products - see the box at the right for more information). The publication schedule can range from weekly, to monthly, to a period of several months at a time. Typically, current awareness publications and practitioner materials are published in this format, as the information they contain is time sensitive for accuracy.

The standard for updates varies with the type of publication. Current awareness publications usually add a new set of pages to a binder as the publication schedule dictates (daily, weekly, monthly, etc.). The binders may cover anywhere from a month to a year, and act as archives for the title. Each set of pages act as an issue covering the latest developments for the subject of the publication.

Titles that are treatises are usually updated by replacing existing pages throughout the book with new ones. Normally, the new pages have the same page numbers, although they can vary depending on the needs of the publisher. For example, a single page covering pages 10 and 11 can be replaced with 10, 10A, 10B, 10C, 11, 11A, and so on. There are other variations on this that a publishers can use.

Publishers tend to add release dates and numbers to the bottom of the page, which gives a sense of currency to the information contained on that page. A current release page (although not always) indicates both the date and number, if any, of the most current update to the volumes. This page, at least, gives some type of notice as to when the book was last updated.
