Supports web catalogues of different library system vendors, see our website or wiki for details.
The underlying code that the app uses to connect to the different supported OPAC software systems and parse

projects because it does not depend on Android APIs. More information about the library can be found in
its own README file.
We'd like to invite you to contribute to our project, e.g. by improving the user interface or adding support
for new libraries. Additionally, you could help to extend our test suite to increase this number: 
Checking out the project with Android Studio should be fairly straightforward, but we also have a little bit of information in the project wiki. Contributions are best submitted via GitHub pull requests.
If you get stuck anywhere in the process, please do not hestitate to ask us anytime at info@opacapp.de.
