COPS is a Calibre library viewer - or libraries, since you can view more than one library simultaneously.
COPS’s main advantages are :
- No need for many dependencies.
- No need for a lot of CPU or RAM.
- Not much code.
- Search is available.
- 100% OPDS valid code (checked with http://opds-validator.appspot.com/).
