"Gregg Martinson  submits, for your interest and/or approval the latest version of his Link-Checking URL Database for schools and Libraries that want to keep collections of preselected links but are concerned about link rot and the unstructured web. The program is written in Pure PHP. Runs on Mysql and is based on PHPLinks. New Additions in the 2.0 version include a new graphical style, googling within the program and the ability to link it to your OPAC. He offers technical support for installation and trouble-shooting for free(although you get what you pay for...) Check it out at The sourcefore page ."
