A brief statement on the advantages of using computer output microform (COM) for library catalogs introduces a general plan for implementing such a catalog in an academic library. The factors involved and types of decisions that must be made are discussed for each of eight steps in the process: determining the objectives of the catalog; choosing the format; data elements to be used; the visual presentation of the data; choosing a microfiche reader; determining the number of readers needed; choosing a service bureau; and user instruction. A formula for determining the monthly cost of maintaining the COM catalog is appended. The more than 60 references provided are listed in subject categories. (RAA)
