Now software questions

Scanners the last time, this time it’s presentation software. Or is that digital library software? Collection management software? Our original pilot project went up on a very old version of Greenstone, and again I am having trouble turning up anything more than Greenstone and CONTENTdm (Perhaps the google-fu is weak in this one.) Our Herbarium uses KE Software’s kEMu for its collections, and while it seems strong in some areas, I have some reservations about its use for digital library collections, mainly that I can’t find a whole lot of libraries using it. (Also, it doesn’t appear to have any MARC support.) Again, is there something I am missing? Are people just using LAMP stacks for this?Are most installations just homegrown? Lots to learn…
