While it is easy to add a bunch of libraries using the same computer system (which is why our list of libraries is growing very fast), it is rather hard to add a library using a different computer system that we do not yet support.
If your library is not in our list, this can be for two reasons:
Sadly, OPAC is just short for Online Public Access Catalogue and is the name of a whole category of software. We only support a limited list of software products. You can take a look at the Compatibility list, or you can just use the form below the list of libraries to ask us.
As the Web Opac App itself does not implement barcode scanning, it requires a third-party barcode scanner app to search by ISBN. We aim to support as many barcode scanner apps as possible, but we can only support those that expose a public interface we can utilize. The following are known to work:
The apps by Scan Inc., „ScanLife“ by Scanbuy and „NeoReader“ by NeoMedia are known not to be supported.
While the adding of new libraries is not hard, there is still some technical configuration to be adjusted. This would not only look irritating in the app’s user interface, but also make it very hard to track down errors. We believe it would do more harm than help, so we do not provide this possibility.
However, if you have some programming experience, you can add a new library and send us a patch or pull request!
This answer depends on the library. The rule of thumb is that the encryption level is exactly the same as when you access your library’s website with your phone’s web browser.
Starting with version 2.0.32, the app displays a yellow warning when creating or changing an account for a library that does not support encrypted connections.
There are multiple possible reasons. We have listed some common ones below:
If you have already tried all the suggestions above, please contact us so that we can further investigate the problem.
Your accounts and favorites lists will not be synchronized automatically. Please set up your library accounts on the new device and use the "Export" and "Import" functions in the top right menu of the favorites list. This needs to be done separately for each library where you have a favorites list.
It depends on the library system you use. For some we do not need anything apart from your catalogue address, but for others (BiBer, Bibliotheca), we’ll need an user account with at least one lent item to test some adjustments.
As this project started as a community project, we still accept suggestions from the community and include libraries according to user wishes.
If you really do not want to be included in the list, please contact us at legal@opac.app and we will remove your library with the next update. (Although this never happened before.)
We take privacy very seriously. We mostly solve the problem by not collecting any data at all: The app builds up a connection directly between the user’s device and the library’s server, without any connection to us. More information can be found in our Privacy Policy
Sure! If you want to use our logo, we prepared a few graphics here.
We can’t tell you, because we just don’t know. We know the total number of downloads of our app, but we do not track which libraries our users use.
Hovever, you can track it by yourself: Ask your network administrator to monitor your OPAC for the HTTP user agent “OpacApp/VERSION”.
This highly depends on the size of your library and the desired features. Please contact us at quotation@opacapp.net and our partner subkom GmbH will get in touch with you.
No, and this is on purpose. Android and iOS are very different environments, both in technical and design terms. Our apps aim to natively integrate in those ecosystems to make using them as intuitive as possible. For this reason, the two apps are not copies of each other, but independent pieces of software by specialized developers. They are, however, the product of constant communication and consist of very similar functions.
