If you have the purple book for Level 1 of Conversational Solfege by John Feierabend you may want to insert three-ring binder inserts for the 16 different sections. I have a link to the dividers I purchased and a document for the printable tabs the dividers included.
Works best with Office Depot brand 8 tab dividers.
Will need way to view "zipped" files.
Both PDF and Word Documents.
