pdf filmstrip from folders

Greetings , Any ideas on any plugins or other creative techniques to do the following: A page with folders to drill down to (with searchable pdf files) by periodical\date (this is an archived newspaper site) . So on the page , you will see a for folder (“Tempo”) , with subfolder (“Year”) then subfolder under that (“month”) then display the pdfs .

Caveats –

All pdfs are in media folders in this exact folder structure (24k of pdfs)

Using full text search which works great on a search of the whole site (SearchWP)…

Each page of the scanned newspapers are separate pdf files – not combined per edition

Again , thank you for all the support and help , I appreciate it
