Many institutions use a combination of methods. Please consult the institutional write-ups to read a full description of what each is doing and how they are combining the methods. These lists are meant to connect you with institutions willing to share their experience. They do not attempt to represent the number of institutions using a particular product or the relative popularity of one product versus another. Keep in mind that some institutions started using one application and then switched to another, but would still be listed here under both applications.
Few institutions use only one application.
Most use a combination of applications, deciding which one works best for the various stages of production. This site will serve as the listing of record. For documentation and files need for creating and delivering finding aids in EAD format, please see the EAD files page. The best way to get a sense of how institutions are actually doing this work is to read through the Annotated Implementor Descriptions. Preparation You may wish to convert existing finding aids into EAD format.
