Introduction A corporate library is a special library within corporations for staff that performs critical functions in many businesses and industries. These facilities allow the staff members to collect information, store and reference it when necessary. It is essential to analyze the internal organization of corporate libraries to identify their benefits and drawbacks, core elements, as well as their significant role in an enterprise’s performance. The Comparative Study on Corporate Libraries Frito-Lay Corporate Library Modern sci-tech libraries are functioning within collections of standards, which differ according to their needs. Such standards can be examined in terms of the corporate setting, specifically in the Frito-Lay Corporate Library. After moving to the new headquarters in 1985, Frito-Lay’s management service, technical service, and labor relations became a corporate library. This approach aimed at addressing the informational needs of its workers, as well as manufacturing locations across the United States. The library is run by the manager and includes information and employee services accountable to the director. Apart from books, this library stores a collection of serials, catalogs from vendors, proprietary documents, technical reports, standards, and other relevant information. Engineers are the most persistent users of the corporate library since their department controls the overall aspects of building and sustaining manufacturing plants and machinery. The library’s standards are divided into categories, but there is certain overlapping. For instance, Underwriter Laboratories standards are of the same concern to mechanical engineers as to electrical engineers. When the library lacks access to specific material, interlibrary loan networks are involved and rarely denied. Thus, the Frito-Lay Corporate Library has to constantly control the use of standards it collects to enable the easiest access to the entire collection with CD/ROM systems involved, proper funding, and focus on the development. Based on this, it can be concluded that the main pro of the Frito-Lay Library is a wide variety of materials and samples. Additionally, the information collected within the library can be accessed by all employees, including engineers and workers. The primary downside of this facility is the overlap of some standards and categories. Photo 1. Frito-Lay logo (TeamConnor). Photo 2. Frito-Lay headquarters and corporate library building (gym). Los Angeles County Metropolitan Transportation Authority The Los Angeles County Metropolitan Transportation Authority (Metro) is another example of a special library that combines traditional local services and historical archives. The library includes a dynamic digital collection and a broad virtual following. As described by Fourie and Loe, this library is a “large quasi-governmental agency” that records the fundamental and unique role of transportation in Southern California in terms of its historical and cultural context (88). The primary users of the Metro Library are employees, government agencies, and research institutions. In addition, this corporate library is also used by the general public and supporters of public transit and urban history. The Metro library an
