To view this page, you should have the most recent Java installed
32-bit JRE (Java Runtime Environment) 1.8.0_31.
This Applet will run online in your browser, but it is a hybrid you
can also download, install and run it on your own machine as standalone
application. It will start and run faster if you do that. It will also
work safely even if you have disabled Java in your browser.
This Applet will help you interconvert, tidy up and validate ISBN-10 and ISBN-13s
(sometimes called EANs (European Article Numbers)) ISBN (International Standard Book Number). It tidies them into
standard form with the dashes in the correct places (the rules where they go are quite
complicated). It also validates the group number and the check digit. Just paste the raw
ISBN-10 or ISBN-13 into the top raw box, click Tidy then copy
the tidied ISBN-10 or ISBN-13 from the bottom boxes. A tidied ISBN
looks like this: 0-9600688-8-0 or 0-13-625666-X or 978-0-00-000000-2.
The amanuensis is also available with Java source to download. When you run ISBN
Amanuensis as an application, it is even more automatic. You don’t need to do
manually paste and copying. Just click Paste to convert the current
contents of the clipboard. The tidied ISBN-13 replaces the old the raw text clipboard
contents. This automatic feature is not available in the Applet version because the
Applet sandbox considers it a security risk.
Java Requirements and Troubleshooting
is a signed Java Applet (that can also be run as an application)
to ISBN Validator.
You are welcome to install it on your own website.
If it does not work…
For this Applet hybrid to work, you must click grant/accept/always run on this site/I accept the risk
to give it permission to let you copy/paste.
If you refuse to grant permission, the program may crash with an inscrutable stack dump
on the console complaining about AccessController.checkPermission.
In the Java Control Panel security tab,
click Start ⇒ Control Panel ⇒
Programs ⇒ Java ⇒ Security, configure medium security
to allow self-signed and vanilla unsigned applets to run.
If medium is not available, or if Java security is blocking you from running the program,
configure high security
and add http://mindprod.com
to the Exception Site List at the bottom of the security tab.
Often problems can be fixed simply by clicking the reload button on your browser.
Make sure the Java in your browser is enabled in the security tab of the Java Control panel.
Click Start ⇒ Control Panel ⇒
Programs ⇒ Java ⇒ Security ⇒
Enable Java Content in the browser.
This signed Java Applet (that can also be run as an application)
needs 32-bit or 64-bit Java 1.7 or later.
For best results use the latest 1.8.0_31 Java.
It works under any operating system that supports Java
e.g. W2K, XP, W2003, Vista, W2008, W7-32, W7-64, W8-32, W8-64, W2012, Linux, LinuxARM, LinuxX86, LinuxX64, Ubuntu, Solaris, SolarisSPARC, SolarisSPARC64, SolarisX86, SolarisX64 and OSX
You should see the Applet hybrid above looking much like this
If you don’t, the following hints should help you get it working:
If the above Applet hybrid appears to freeze-up, click
Alt-Esc repeatedly to check for any buried permission dialog box.
If you have certificate troubles,
check the installed certificates
and remove or update any obsolete or suspected defective certificates.
The only certificate used by this program is mindprodcert2015dsa.cer.
Especially if this Applet hybrid has worked before, try clearing the browser cache and rebooting.
To ensure your Java is up to date, check with Wassup.
First, download it and run it as an application independent of your browser,
then run it online as an Applet to add the complication of your browser.
If the above Applet hybrid does not work,
check the Java console for error messages.
If the above Applet hybrid does not work, you might have better luck with the downloadable version available below.
If you are using Mac OS X and would like an improved Look and Feel,
download the QuaQua look & feel
UnZip the contained quaqua.jar
and install it in ~/Library/Java/Extensions
or one of the other ext dirs.
Click the Information bar, and then click Allow blocked content. Unfortunately, this also allows dangerous ActiveX code to run. However, you must do this in order to get access to perfectly-safe Java Applets running in a sandbox. This is part of Microsoft’s war on Java.
Try upgrading to a more recent version of your browser,
or try a different browser e.g. Chrome, Firefox, SeaMonkey, Opera, Safari or Avant.
If you still can’t get the program working
click the red HELP button below for more detail.
If you can’t get the above Applet hybrid working
after trying the advice above and from the red HELP button below,
have bugs to report or ideas to improve the program or its documentation,
please send me an email at.
This program also handles the new Bookland
EAN-13, 13-digit, bar-code ISBNs. It handles both 10-digit and 13-digit
All it does is prepend 978- to the old number and recompute the check digit, e. g.
0-915972-22-0 becomes 978-0-915972-22-7.
0-13-625666-X becomes 978-0-13-625666-3.
ISBN-13 numbers that start with 979 don’t have an
This program displays both the ISBN-10 and ISBN-13, with dashes in the right place,
given either, The new Bookland EAN-13 check digit is computed in an unusual way with
mod 10 and weight 3.
This means the 13-digit ISBN
numbers are always purely numeric. There is never an X check digit as there is sometimes
with the mod-10, 10-digit ISBNs. 10-digit ISBNs
and 12-digit UPCs (Universal Product Codes) are being unified as 13-digit EANs.
for the current version of ISBN Amanuensis. Applet to help you tidy, convert and verify ISBN-10 and ISBN-13 numbers used to identify books. Inserts dashes in the correct places and validates the check digit. It works even more simply as a downloadable application. ISBN stands for International Standard Book Number.
