Lenny

Lenny is a free, open source Lending System for Libraries.

Technologies

• docker for deployment and containerization
• nginx handles patron requests (reverse proxy to app)
• FastAPI (python) as the web & API microframework
• Minio API for storing digital assets (Amazon, Internet Archive, or local flat-file)
• yaml for configuring library-level rules
• postgres for the database
• SQLAlchemy for the database python ORM
• Readium LCP for DRM; see LCP Server
• Readium Web SDK for a secure web reading experience
• OPDS RSS-like standard for syndicating holdings

Endpoints

• /v{1}/api
• /v{1}/manage
• /v{1}/read
• /v{1}/opds
• /v{1}/stats

Installation

First, copy the file lenny_TEMPLATE.env to lenny.env (gitignored) and edit it to have the correct values (such as desired psql credentials).

Second, run docker compose:

docker compose -p lenny up -d --build

Finally, navigate to localhost:8080 or whatever $LENNY_PORT you specified in your lenny.env

Pilot

We're seeking partnerships with libraries who would like to try lending digital resources to their patrons.
