People who like to burrow around in the online logbooks will be pleased with the updated Logbook Search facility. Instead of having to wait perhaps 20 seconds for the results to appear, the logbook page links now appear instantly, even for sites such as Cueva Hoyuca which has 397 logbook entries. The input box will accept both site numbers and partial names.
