This means that to learn all the bib numbers in a system: 1. Look at a new books list or simply find something that was recently added to the catalog 2. Look at source HTML for a bib record. You'll see the bib record number right there. This will give you an idea of how long your process needs to run 3. Have a program systematically guess bib numbers (the system seems to handle this well, but keep sys and network admins in the loop and design your crawler to play nicely -- especially since robots.txt specifically disallows the searches you'd be doing). 4. Periodically, have the program look ahead for new numbers This process tells you which records are being used and which aren't (you may as well harvest the data while you're in the record). Incidentally, this is one of the times that accessing the XML record is useful as that contains the creation date of the record as well as the internal codes. BTW, using XRECORD rather than a regular search is better if there are lots of items because the system doesn't need to combine info from multiple record types into each display. I have used this method on millions of records at a time without any noticeable impact on performance. As sucky as it is, this is sometimes your best option and it's definitely better than trying to work through the gui. One advantage it has over using expect and MARC export is that you can harvest huge databases without having to deal with limits on Create Lists sizes or the system load that running such large lists imposes. Note that periodic crawlings are necessary to identify deleted/changed records kyle
