13digit ISBN support in v0.5

With v0.5, isbnsearch has completed the adjustments to the database tables and the scripts to correctly verify the 979 namespace.

Although 13 digit ISBN numbers won't be in use for a while yet, isbnsearch has moved to a 13 digit system by adding the 978 and the appropriate checksum to existing records using v0.5.

All sites should now to upgrade to v0.5. All web pages and scripts will continue to display ISBN values in 10 digit form for some time.... read more

isbnsearch prepares for 13 digit ISBN numbers

http://www.collectionscanada.ca/iso/tc46sc9/isbn.htm

The 13digit ISBN is an extension of existing EAN barcodes which isbnsearch already supports. As well as using the existing 978 prefix (plus check digit), the 979 prefix will also be used for ISBN details.

A 13 digit ISBN could therefore start 9-78 or 9-79. All existing ISBN's will remain available as 9-78 and any 10 digit ISBN entered will be converted to 13 digits using 9-78.... read more

isbnsearch-0.41 released

isbnsearch-0.41

The greatest limitation on any isbnsearch site is the size of the database files. On webhosts, webspace costs money and most hosting accounts offer hundreds of time less storage than a home system. This can translate into
millions of extra ISBN records. To tap into this resource, v0.41 of isbnsearch has been adapted to access systems that are installed behind firewalls and using dynamic or static IP broadband connections. These portals are called 'private' and divided into 'internet-visible' and 'non-visible'.... read more

Development continues

After a break to deal with other projects, I've been spending time again with the isbnsearch code. The next release is set to include more code for private sites to participate. These sites offer very large storage capacity and could be a useful resource for heavily loaded isbnsearch indexservers. The main code has had a few tweaks and current CVS HEAD will be folded into the next release, 0.41, in the next few weeks.

isbnsearch 0.3-3 released

A distributed search portal of common sources of ISBN numbers, with permanent caching of results. To provide a free software, open-source, interface for ISBN retrieval using HTML, SQL or XML to be independent of any toolkits or software.

The largest change in 0.3-3 is in the devel/newservers.sql file, adding over 400 new Z39.50 servers. All existing servers have now been verified and the results for all LoC Gateway servers are included in the devel/servers.html servers reports included in the package. To avoid duplication and to keep the size of the package small, the two comprehensive server reports (LoC Gateway and Net::Z3950::AsyncZ) are not included. Instead, the smaller Gateway interface reports in the package include full error status output and link directly to the comprehensive Gateway server report on the isbnsearch SourceForge home pages, which also host the AsyncZ comprehensive server report. There are small changes in the documentation. There are small changes in the two cron perl scripts and in the MARC output isbn.pl script. No database table structures have been changed.... read more

Bug fix patch for isbnsearch release 0.3-1

There is a bug in how portals notify indexservers as part of the distributed framework. This is currently preventing indexservers from retrieving range data from new portals and therefore in referring queries to the correct portals.

The required variables are being overwritten because the relevant lines of PHP appear too late in the script. The patches for each of the xml/isbn.php, html/isbn.php and sql/isbn.php files simply move the relevant lines to a higher position in the script. ... read more

LUG co-operation

A few new portals should appear soon - I've had offers of help from my local LUG! Great news!
Anyone else interested in providing MySQL space for their own server, please join the mailing list.
