We have a complete list of supported libraries that you can check for your local library. If you library isn't on the list, please send us a message and we'll see if we can add it. In most cases, we can get your library added within a few days.
Why can't I select eBooks for my library?
At this time, we only support results from Overdrive and select 3M Digital Books powered digital collections. If your library has an Overdrive or 3M Digital Books powered digital collection, we may have missed it and we'd be happy to add it
Why can't I select Books for my library?
At this time, we only support results from a select set of catalog systems. In some cases, library systems do offer an Overdrive powered digital collection, and we've enabled the option to at least get those results.
Can the extension show results for more than 1 library?
Yes, the extension can show results from multiple library systems! You can add as many libraries as you like on the configuration page
Why does the extension keep showing no matches found?
Although it's possible that your library doesn't have a copy, it's also possible you've discovered a bug in the extension, and we'd love to get it fixed right away. Send us a message with the name of the library and a few example books where you're seeing the problem. There's also a chance that your library has changed their catalog recently, and we haven't noticed, in which case we'll fix it as soon as you let us know about it!
When I click the Reserve a Copy or Place Hold button, why is the book listed isn't the same one I saw on Amazon?
We depend on the results that your library's catalog returns, similar to when you search on their site yourself. Sometimes the results returned aren't very good. If you do encounter a particularly poor match, let us know and we'll see if we can improve our ability to look for a match in those results
Why do the eBook results never match the exact title? Why are there all of these unrelated results under the eBooks results?
We use Overdrive's search results when we try to look up a book, and sometimes their search results don't return anything matching the title. We're working on figuring out a way to improve those result listings, but have decided to show all of the similar titles until we can improve our own display abilities.
How and when do you redrive revenue? (i.e. what's the
At the moment, the extension is free for all, and does not
produce any revenue. We are working on some new features that will be
provided as 'premium' upgrades while keeping all of the existing
functionality free for users.
What and how do you track my books?
We take user privacy seriously and, unlike other tools, we do
not track your browsing behavior. The Extension was designed to perform
searches directly at your library, rather than through a middle-man, in
part as a way of ensure user privacy. We do track some anonymous metrics
surrouding the general use of the extension (for example, what versions
of the extension are installed and which libraries are in use, as a
way of ensuring we keep popular libraries working. If you have
questions, we are more than happy to answer them if you contact us.
Why does the extension require permission to "Read and change all your data on the websites you visit"?
This is a common question, and a very good one. Note that
the library extension does not track your browsing history or store any
information about the pages you visit or anything you enter on those pages.
To understand the permission and how and why it's used, let's look at
how browser permissions work and each portion of the permission above.
The permissions given to a browser extensions come from configuration
that the extension provides to the browser. This configuration
indicates the capabilities it requires in order to function. These
permissions are a fixed set of values at the time that the extension
is installed. In the case of the Library Extension, we request
a permission that allows us to run code within the pages that you are
browsing (called 'content scripts') that is defined as 'Read and
change all your data on the websites you visit'.
The content scripts we run need to be able to 'read all of
your data' on the page in order to find the search terms that
will be used to try and find matches at your library. This information
is limited to trying to determine the type of item (book, CD, etc),
the title, the author, and any ISBN numbers, as defined by the various
pages we run on.
The 'change all of your data' permission is required
so that we can present the results on the same page. It's a strongly worded
permission, and rightfully so, as anything on the page is open to modification
by the script. However, we add one special section on the page within which we
displayed the library search results for users.
Finally, the permission allows for the above on all 'the
websites you visit'. The extension does run the content
script for every page, where it checks to see if it is on one of the
following sites, and only then will it actually do the work described
• libraryextension.com (this site)
If the page you are on is not one of the above pages, the extension
stops running. There is no tracking nor any other messages passed back
regarding the pages that you are visiting.
The reason for running on all sites is that although the extension
supports only the sites listed above today, we do occassionally add
support for a new site or feature. Unfortunately, the permissions
model provided by the browser is a 'set once' model when the extension
is installed, and cannot be changed incrementally. Adding support for
any new site would be a permissions change that would disable
the extension for most existing users.
If browsers were to provide a more user-selective way toward
choosing which sites can be enabled or disabled, we would certainly look at
taking advantage of that mechanism for limiting where the extension is
permitted to run.
How do I check what version of the extension is installed?
You can find the version of Library Extension on the page
chrome://extensions. If it has not updated yet automatically,
you can force an update by checking the 'Developer Mode' checkbox in
the upper corner of the page, and then clicking on the 'Update
Extensions Now' button that shows up.
How can I force an update to the latest version?
If you have already installed the extension, you can check to
see if you have the new version (it will usually install itself
automatically) on the page chrome://extensions. If it has not
updated yet automatically, you can force an immediate update by
checking the Developer Mode checkbox in the upper corner on
this page, and then clicking on the Update Extensions Now
button that shows up.
How can I find the configuration screen?
You can find the configuration screen by visiting
in Chrome, or by visiting chrome://extensions, find Library
Extension and click on the Options link.
